Question

Esterification of a reacemic alcohol (ROH) with an optically active acyl chloride (R'COCl) gives :

• A. two diastereomeric esters
• B. a recemic ester
• C. a single optically active ester
• D. one optically ester and one optically inactive ester

Answer 1

The correct option is A two diastereomeric esters

Diastereomers are stereoisomers that are not mirror images of one another and are non-superimposable on one another. Stereoisomers with two or more stereocenters can be diastereomers.
So racemic mixture of alcohol gives diastereomers with optically active acyl chloride as
