TRATEGY PROBLEM 18 Draw enantiomers for each of the following using a. perspective formulas. b. Fischer projections. CH, 1. CH3CHCH,OH 2. CICH,CH,CHCH,CH, Br CH, 3. CH3CHCHCH; OH
Draw all stereoisomers associated with 2-Bromo-3-methypentane. Draw the Fischer projections for all stereoisomers associated with 2-Bromo-3-methypentane. Clearly label all stereoisomers as either enantiomers, diastereomers, or meso. Place the lowest priority groups in two vertical positions in final display. SHOW ALL WORK CLEARLY. Thank you!
For 2-chloro-3-hexanol: Draw the structure of all the possible stereoisomers with Fischer Projection and Perspective Formulas showing both eclipsed and staggered conformations). 2) Assign the configuration of all chiral centers with R or S. (3) Give the complete IUPAC name for each stereoisomers. (4) Indicate the relationship among the structures, indicating which are the threo or erythro enantiomer, and diastereoisomer pairs.
Draw all the stereoisomers (redraw the first with the proper 3-D representation) of the compounds below. The configuration for the first isomer you should draw is provided. Assign R or S configuration to each chirality center in the additional isomers. Indicate the stereochemical relationship (diastereomers, enantiomers, meso compounds) between the first isomer and each of the others. The configuration for the Fischer Projection has been omitted, since stereochemistry can be determined from a 2-D structure. You do not need to...
5. For the following set of Fischer projections answer each of the questions below by circling the appropriate letter(s) or letter combination(s). Hint: Redraw the Fischer projections with the longest carbon chain in the vertical direction and having similar atoms in the top and bottom portion. Classify all chiral centers in the first structure as R or S absolute configuration. (X pts) a. Which are optically active? b. Which are meso? c. Which is not an isomer with the others?...
IX. (12 pts) Draw Fischer projections of all possible stereoisomers of 3-bromo-2-chlorobutanoic acid: CHaCH(Br)CH(CI)CO2H. Determine the R/S configuration of each stereocenter. Indicate the relationship between each pair of stereoisomers.

Take particular care to indicate three-dimensional stereochemical detail properly. -
1. Consider the following Fischer projection formulas of 3-amino-2-butanol. Decide which pairs of the formulas are related as enantiomers, which are related as diastereomers, and which represent identical molecules. Assign R or S absolute configuration to C2 and C3 for each structure, and then decide. List your results by letters in the spaces provided below. (5 pts) CH2CH3 O CH3CH2 - NH căH HS CH2CH3 H.
