Chemistry - STEREO ISOMERISM Question with Solution | TestHub

To resolve a racemic mixture of 3-methylpentanoic acid, a chiral resolving agent is needed. This agent must be optically active and capable of forming diastereomeric salts with the acid. Diastereomers have different physical properties (e.g., solubility), allowing for their separation.

Options B, C, and D are all chiral alcohols, which can be used to form diastereomeric esters or salts (after conversion to an amine or by using a chiral amine base) with the carboxylic acid. Propan-2-ol (Option A) is achiral and thus cannot resolve the mixture.
