Question

multiple choice 2 points draw structures consistent with the names given below. a. (2r,3r)-2,3-dibromo-4-methylpentane b. (r)-1-bromo-1-iodopropane c. an achiral stereoisomer of 1,2-dimethylcyclopentane

Explanation:

Step1: Analyze (2R,3R)-2,3 - dibromo - 4 - methylpentane

The structure in option A matches the given name with bromine atoms at 2nd and 3rd carbon with R - configuration and a methyl group at 4th carbon of pentane chain.

Step2: Analyze (R)-1 - bromo - 1 - iodopropane

The structure in option B has bromine and iodine attached to the first carbon with R - configuration in a propane chain.

Answer:

a. A
b. B
c. Information about option C is incomplete in the provided image, so cannot be determined from the given content.
