Draw a Fischer Projection for the following chiral, tetrahedral carbon: Br H HO CH2CH3 OH CH 2CH 3 Br H There are multiple correct answers for this problem! 2. Assign R or S to the following molecules: You must put the lowest priority group in the BACK (or top/bottom for Fischer Projection) before making R or S assignment (a) (b) 3.
Web24) Draw the Fischer projection of (S)-2-hydroxybutanoic acid, CH3CH2CH(OH)COOH. 25) How many enantiomers are there of the molecule shown below? OH OH A. 6 B. 2 C. … WebVideo transcript. - [Instructor] Here we have a pair of enantiomers. On the left we have (R)-Carvone, and on the right we have (S)-Carvone. Both of these compounds have the same Melting point, the same Boiling points, and the same Density. However there are a few important differences.
WebExample: Answers to problems on the worksheet: Comparing two molecules: Either assign R versus S to each configuration or rotate the Fischer Projections so the centers can be evaluated for matching or not matching. The Same: all centers match (R versus S, or by alignment of the Fischer Projection) WebNow, 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 …
WebUsing the Fischer projection notation, the stereoisomers of 2-methylamino-1-phenylpropanol are drawn in the following manner. Note that it is customary to set the longest carbon chain as the vertical bond assembly. The usefulness of this notation to Fischer, in his carbohydrate studies, is evident in the following diagram.
