molecule in the mirror, and I would have the enantiomer, so this would be the is going to the right, and it's going up at us, so that OH is going to the right, and it's going up at us, and then if I look at -glucose: in the conventional Fischer projection, a wedge/dash version of a Fischer projection, and finally in the 'zigzag' style that is preferred by many organic chemists. draw the Fischer projection of a monosaccharide, given its wedgeandbrokenline structure or a molecular model. How can I convert S-1-fluoro-2-chloropropane to a Fisher projection? A good strategy here is to convert the Newman projection to a bond-line structure and from there get to the Fischer projection as we did above. So you could do the same 1. So, this would be S And if you do that, you will find that it is also R. So you can go ahead and It is as if we had wrapped the chain around a cylindrical tube. Start by mentally converting a 3D structure into a Dashed-Wedged Line Structure. How can I convert 3S,4R-dibromoheptane to a Fisher projection? I have a question: how do you do Fischer Projections for compounds with a carbon-carbon double bond? at my chirality center. Who are the experts? Identify all the chiral centers and determine the absolute configuration asRorS: What is the relationship between these two structures? In the above diagram, if x = CO2H, y = CH3, a = H & b = OH, the resulting formula describes (R)-()-lactic acid. Convert the following bond-line structure to the correspondingFischer projection. Direct link to Myat TR's post How can I know 3-D struct, Posted 7 years ago. Since this is not the usual way in which we have viewed such structures, the following diagram shows how a stereogenic carbon positioned in the common two-bonds-in-a-plane orientation ( xCy define the reference plane ) is rotated into the Fischer projection orientation (the far right formula). projections are another way of visualizing molecules Conversion of wedge dash to Fischer projection The. Organic Chemistry Study Materials, Practice Problems, Summary Sheet Guides, Multiple-Choice Quizzes. Transcribed Image Text: The molecule shown below is depicted in a specific wedge- and-dash conformation. Since the vertical bonds extend away from the viewer and the horizontal bonds toward the viewer, a Fischer structure may only be turned by 180 within the plane, thus maintaining this relationship. down in space like that. They are all inverted from R to S and S to R. If you need to draw a diastereomer of the molecule, you need to switch only one chilaity center or, alternatively, switch all except one. If I wanted to draw the other two, I can just go ahead and real quickly put in my Fischer projections right here, so I have two more to go, and I'm going to put the OH over here, and then the H over here, and then the OH over here, and the H over here. acid functional group, and then I have a hydrogen over here, and then I have an OH group over here, and then I have a CH3 here, so this is a Fischer projection, this is the Fischer The green balls (atoms) are pointed toward the screen. Convert the following Bond-Line, Newman and Fischer projections as indicated below: The answers can be found under the following article: Converting Bond-Line, Newman Projection, and Fischer Projections. For example, this is how the following bond-line is transferred to a Newman when looking through the C1-C2 bond from the top-left: I have noticed that many students struggle with this concept and after trying different approaches, I spontaneously drew a person instead of the eye for the view direction and it turns out to be a game-changer. Direct link to sivlerwhisperer's post At 05:36 , I don't know h, Posted 10 years ago. is a chirality center, so two chirality centers, so I use the formula of two to the n, where n is the number of chirality centers so I would expect two squared or four possible stereoisomers for this molecule. this carbon right up here, so we'll make that carbon this one, and you can see that the OH attached to that carbon Just like at carbon 2, the H (lowest priority) for carbon 3 is coming toward us, rather than away, so the counterclockwise direction is reversed from (S) to (R). thing with this one. So the #"OH"# groups on #"C-2"# and #"C-4"# become wedges. conversion from Fischer, Haworth, and chair structures. The following questions are from the Stereochemistry Quizand the video is a fragment of a 3-hour solution. Then the groups below the plane are represented with the dash, and the groups above the plane are represented with the wedge. . And I would have my OH Well I have a hydrogen, a carbon, an oxygen and a carbon. So, first, decide the direction you are going to use. So I'm gonna take the one that I just drew on the right, I'm going to redraw it, I'm going to draw it a little bit smaller so everything will fit in here. the absolute configuration at carbon two here. The wedge and dash representations of stereochemistry can often become cumbersome, especially for large molecules which contain a number of stereocenters. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. Don't worry, you're not the only one confused by this. Remember each chirality center is determined (R) or (S) individually. The Fisher structures of the most common monosaccharides (other than glyceraldehyde and dihydroxyacetone), which you will encounter most frequently are shown below. Make certain that you can define, and use in context, the key term below. Thank you. What is the relationship between Ha and Hb in the given compound, trans-1,3 dichlorocyclobutane. The green balls (atoms) are pointed toward the screen. The problem of drawing three-dimensional configurations on a two-dimensional surface, such as a piece of paper, has been a long-standing concern of chemists. So this is one of the four. Dr. Dietmar Kennepohl FCIC (Professor of Chemistry, Athabasca University), Prof. Steven Farmer (Sonoma State University), William Reusch, Professor Emeritus (Michigan State U. In a Fischer projection drawing, the four bonds to a chiral carbon make a cross with the carbon atom at the intersection of the horizontal and vertical lines. construct a molecular model of a monosaccharide, given its Fischer projection or wedge and dash structure. Determine if carbon #2 in D-glucose is R or S. Expert Answer. This carboxylic acid functional group, this is the top of my head right here, then that would make this go at the top of what I'm looking at, and so, that is going The reason being is that it allows us to only focus on one central carbon, which make things a little bit easier. In this post, we will learn how to convert between Fischer, Bond-line, and Newman projections in different orders. Often the simplest way to check is to construct a molecular model corresponding to each projection formula, and then compare the two models. So at carbon two, what do I have? find that our OH group is on the right, coming out at us. Make certain that you can define, and use in context, the key term below. So here I have a saw horse projection of one of the possible stereoisomers. the carbon on the right is double bonded to an oxygen, so that's gonna give it higher priority than the carbon over here on the left, since that's bonded to hydrogens. sometimes a carboxylic acid functional group over here on the right. just make it much easier when you're working with carbohydrates. It's called lactic acid, So that's a quick summary ahead and drawn one of them, as a saw horse projection. If the lowest priority group is on a horizontal bond, the positions of the remaining groups give the wrong answer (you are in looking at the configuration from the wrong side), so you simply reverse it. In a Fischer projection, the carbon atoms of a sugar molecule are connected vertically by solid lines, while carbon-oxygen and carbon-hydrogen bonds are shown horizontally. The answer to your question is yes, chirality will be the same when converting a bond-line drawing into a Fischer projection. Some people can't visualize, or understand, how this happens so the trick is that whenever the lowest priority (this time hydrogen) is not facing the back, the answer R or S will be opposite. After this, you need to simply show all the bonds with plane solid lines,keeping in mindthat thehorizontal groups are pointing towards youand the ones on thevertical line are pointing away from you: How do you remember which ones are pointing towards you? Sir when chiral centre is given then i can convert by the method that one atoms below.or above the plane of paper are lie on horizontal line and other lie on same plane on a vertical but when it come to more than one chiral centre i am confuse .when question asks predict wether pair entaiomers or something. How can I convert R-3-methylhexane-3-ol to a Fisher projection? Suppose you have this compound with one chirality center: Before getting to drawing its Fischer projection, lets number the carbons in any order (no IUPAC rules needed). There are eight stereoisomers of 2,3,4,5-tetrahydroxypentanal, a group of compounds referred to as the aldopentoses (aldo- since the oxidized carbon is an aldehyde and -pentose since the molecules contain 5 carbons). The structure A represents Fischer Projection of a compound. Direct link to Joao Faria's post I have a question: how do, Posted 5 years ago. When deciding whether a stereocenter in a Fischer projection is R or S, realize that the hydrogen, in a horizontal bond. Its all here Just keep browsing. and draw my aldehyde. Could very old employee stock options still be accessible and viable? And I'm gonna go ahead and label them, I'm gonna label this first one here, stereoisomer A, stereoisomer B, stereoisomer C, and stereoisomer D. Well, C and D are mirror images of each other, so they are enantiomers of each other so these are enantiomers. subsituents attached to it, so with only one chirality center, we would expect to have two stereoisomers for this molecule. An alternative way to represent stereochemistry is the Fischer Projection, which was first used by the German chemist Emil Fischer. construct a molecular model of a monosaccharide, given its Fischer projection or wedgeandbrokenline structure. Show transcribed image text. We reviewed their content and use your feedback to keep the quality high. of those straight lines are where our chirality centers are. Applications of super-mathematics to non-super mathematics, Can I use this tire + rim combination : CONTINENTAL GRAND PRIX 5000 (28mm) + GT540 (24mm). The stereochemical formula for (R)-lactic acid can be drawn using the wedge-dashed structure and Fischer projection method. However, arabinose and xylose are not epimers, since their configurations differ at both C-2 and C-3. this would be an OH, this would be an H, this would be an OH, this would be our CH2 OH, and then at the top we I know a Fischer projection tells me that if it's a horizontal line, everything's coming out at me, so my OH is coming out at me, and my hydrogen is coming out at me. Direct link to Tim's post You must remember that Ja, Posted 10 years ago. Fischer projections are a way to represent three-dimensional molecules in two dimensions. Excellent question, Luke. Learn more about Stack Overflow the company, and our products. More helpful than 1000 words. How to find whether the two compounds are enantiomers or diasteromers? the one we just drew and let's get the other Direct link to Ernest Zinck's post The molecule shown at 5:3, Posted 3 years ago. enantiomer to this molecule, I would just have to Let's see which enantiomer is actually coming out at me, so in the little trick I showed you in the earlier video, if the hydrogen is coming out at me, all you have to do is reverse it. Why was the nose gear of Concorde located so far aft? a Fischer projection of R lactic acid, what I would do is I would put my eye right here, and I would stare down This means, for example, when you are converting a Fischer projection to a bond-line, you can simply draw the zig-zag with the correct number of carbons and add the groups by randomly assigning them wedge and dash notation. So this carbon is my construct a molecular model of a monosaccharide, given its Fischer projection or wedge and dash structure. reflect it in a mirror. And then my other hydrogen attached to my chirality center we have over here. The wedges are now on the right, and the dashes are on the left. When determining R or S, the lowest priority substituent needs to be facing towards the back, which can be done "turning" the molecule at the chirality center that the hydrogen is attached too. draw the wedge and dash structure of a monosaccharide, given its Fischer projection or a molecular model. Start by mentally converting a 3D structure into a Dashed-Wedged Line Structure. Organic Chemistry Study Materials, Practice Problems, Summary Sheet Guides, Multiple-Choice Quizzes. On the back carbon, we have Br on the left, and H on the right: In order to convert a Newman projection to the corresponding bond-line structure, you need to look at it from the side. Oops! Ask me anything over Zoom whenever I am online! So here is carbon two right here. When you flatten the structure onto the surface of the cylinder, you get the Fischer projection of D-glucose. Practice and use your molecular model set to help you with the visualization aspect. Are there conventions to indicate a new item in a list? away from me in space, so we would use a dash to represent that, and so we could go ahead and draw our C double bond to an O and then an OH going away from me, and then if I look at Converting Wedge-Dash Structure to Fischer Projection. We must view a wedge-dash formula from the correct angle to convert it to a Fischer projection. The Fischer Projection consists of both horizontal and vertical lines, where the horizontal lines represent the atoms that are pointed toward the viewer while the vertical line represents atoms that are pointed away from the viewer. However, arabinose and xylose are not epimers, since their configurations differ at both C-2 and C-3. Well, if I'm staring down this way, I could draw a line right here to represent my flat sheet of paper, and I can see that both my hydrogen and my OH are above my sheet of paper, whereas my carboxylic acid and my CH3 are below my sheet of paper. Lets start with the conversion between bond-line structures and Newman projections. And therefore, it must have the same absolute configuration of all the chiral centers.

How can I draw Fischer projections from Haworth? Accessibility StatementFor more information contact us atinfo@libretexts.orgor check out our status page at https://status.libretexts.org. So it looks like it's S, but since the hydrogen If the configuration at C-4 is kept constant (R in the examples shown here), the four stereoisomers that result will be diastereomers. This means that the molecules cannot be placed on top of one another and give the same molecule.$\ce{^2}$. Answer Which of the following wedge-and-dash structures represents the Fischer projection shown below? Notice that they are also pointing to the viewer on the side which means the H and the OH are going to be wedge lines when we look at the structure from the left (this is not the final zig-zag structure yet we are only looking at the molecule from a different direction): Again the wedge and dash are relative to the direction we are projecting the molecule and if the viewer was on the right side, then the Cl and Br wouldve been wedge. How does a fan in a turbofan engine suck air in? Let's do one more thing Let's go back up here and stare down that carbon two chirality center, and let's see what we would actually see if we do that. reflected in my mirror, and then I'd go ahead and So I have my OH coming out at me, my hydrogen coming out at me. Figure C Figure D. Lets start with this 3D image and work our way to a dashed-wedged image. Have . The main carbon chain here is represented on plane in a zigzag fashion. Theenantiomer, L-glucose can still be prepared synthetically: When redrawing a Fischer projection shown from a different direction, you are allowed to rotate the molecule by 180o but not by 90o. So I'm going around this way. Also, you are asking two questions, so you should probably post two questions. Question: Convert the following Fisher Projection to a wedge/dash. Sighting towards the carbonyl C, if the OH is pointing to the right in the Fisher project, it should be pointing to the right in the wedge and dash drawing, as shown below for D-erthyrose and D-glucose. For those draw a wedge and dash line drawing of the molecule. Now that we have our Dashed- Wedged Line Structure, we can convert it to a Fischer Projection. The following is conversion of molecules with two chiral centres from wedge to fischer projection yhrough a series of operations as shown below. Draw a Newman projection of this molecule in the same conformation. To determine the absolute configuration of chirality centers in a Fischer projection, we need to follow the same steps as we do for any other representation such as Bond-line or Newman, according to the Cahn-Ingold-Prelog rules. Fisher projections show sugars in their open chain form. So too that in a Fischer projection, each chirality center is drawn individually. So this is yet another And when I compare these two carbons to each other, I know (Numbering starts from the top)" I don't know what to make of this. When studying this section, use your molecular model set to assist you in visualizing the structures of the compounds that are discussed. As a reminder, the horizontal line represents atoms that are coming out of the paper and the vertical line represents atoms that are going into the paper. this bond right here, and we're going to see if we can draw the Fischer projection for this molecule, so, what do we see? So this would be an H, Exactly what I was looking for. Let's take a look at a carbohydrate since Fischer used Fischer projections for carbohydrates specifically, so here I have a carbohydrate, and if I were to number this carbohydrate this carbonyl would get a number one and then this will get We will show the ones on the sides with wedge lines and the others with dashed lines: There are two wedge and two dash lines which may look strange to you since we always have one of each and then the two solid lines, but it is okay-it all depends on the direction we are looking at the molecule. in the stereochemical nomenclature used for sugars): Below are three representations of the open chain form of. So this aldehyde functional group is going away from us, so we can go ahead and Okay if I wanted to draw the So at carbon two, at this carbon it is R. So you can do the same thing with the chirality center The direction is usually given with an eye symbol or an arrow. The aldehyde group, however, wouldve been on the right side and the methyl on the left. Browse other questions tagged, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site. Well it would be carbon versus carbon, so the top, I have A more selective term, epimer, is used to designate diastereomers that differ in configuration at only one chiral center. It's a way to quickly draw multiple sugars and compare them since it's easy to spot the asymmetric carbons on a Fischer projection. For this, we are going to draw the molecule and simply show all the bonds with plane solid lines, keeping in mind that the horizontal groups are pointing towards you and the ones on the vertical line are pointing away from you: So, how do you remember which ones are pointing towards you? The carbon above the chirality center (carbon 1) does not have 2 oxygens bonded to it but you count it as 2 because of the pi bond when assigning absolute configuration. Since there are three chiral centers in this constitution, we should expect a maximum of 23 stereoisomers. So let's see if I can fit my mirror in over here. Can the Spiritual Weapon spell be used as cover? That's easy to visualize for 3C molecules. In the following practice problems, you can practice converting Fischer projections to bond-line representation and assigning the R and S absolute configuration of chirality centers on Fischer projections. draw a straight line, since we're looking straight down at it, and once again, we will absolute configuration to that chirality center, b) Label all stereocenters as R or S. c) Indicate any pair of enantiomers, diastereomers and the meso compound if present. Note that it is customary to set the longest carbon chain as the vertical bond assembly. Therefore, the orientation of the three remaining substituents is reversed to create the correct answer or a counterclockwise circle means R, and a clockwise circle means S. For carbon #2 in D-Glucose substituent 1, 2, and 3 form a counterclockwise circle so the carbon is R. To make a Fischer Projection, it is easier to show through examples than through words. Think of . The zig-zag will have the methyl on the bottom-left side and the ethyl group on the right side respectively: Now, to transform the bond-line into a Fischer projection, we can look at from the top such that the methyl group goes on the top of the Fischer projection: Remember, to flip the bond between the carbons in order to have the horizontal groups as wedge lines before drawing out the Fischer projection: Below are some practice problems converting between Bond-Line, Newman, and Fischer projections.
