Draw the enantiomers of 2-methyloxirane
2. (8 pts) For the following molecule, draw 2 pair of enantiomers (that's 4 isomers total), and circle each pair. OH CI ОН Нон-с CH3 0
Draw a pair of Diastereomers Draw a pair of Enantiomers Draw a pair of constitutional isomers Draw a compound without a chirality center Draw a meso compound (10 points) Draw structures with the molecular formula, C.HgF2 that match each of the constraints. Pairs should contain two structures that have that relationship. Structures that do not have the correct formula score no points.
For the following reactions, predict the MAJOR product(s). If a pair of enantiomers is expected, draw both enantiomers. NaSH Cis-1-bromo-3-methylcyclohexane acetone OTs 1. NaI/acetone 2. NaCN/DMF CH3 NaCN H,с. Br CH3 Бшн.
Draw BOTH products and label them as either enantiomers or diastereomers:
1. Draw the two enantiomers of trans-1,2-Diaminocyclohexane and assign stereochemistry (R or S) to both of the chirality centers in each of the enantiomers.
and this too please Problem III: Draw the enantiomers of the following molecules: Prohlam IX
Draw Fischer projection and line/wedge diagrams for the two enantiomers of usnic acid.
Write a mechanism for the following competing (SN2 and E2) reactions. Draw the pair of enantiomers obtained in the following reaction.
2. what is the ratio of enantiomers in a mixture with an enantiomeric excess of 50%? 1. If (R)-2-bromobutane has a specific rotation of -23°, what is the value of [a], for dextrarotatory 2- bromobutane at the same temperature? +23 2. What is the ratio of enantiomers in a mixture with an enantiomeric excess of 50%? 3. a) Draw the structure of (2S,3S)-2,3-difluorobutane in an extended zig-zag line drawing using wedged and dashed bonds where appropriate.
A pair of theoretical enantiomers is named below. For each stereoisomer, draw the structure. Be sure to specify the stereochemistry via wedge-and-dash bonds
