Question

The major product (ester) of the following reaction is?

• A. A single stereoisomer (optically active)
• B. A mixture of diastereomers (both optically active)
• C. A racemic mixture (optically inactive)
• D. A mixture of four stereoisomers (two racemic mixtures)

Answer 1

The correct option is A A single stereoisomer (optically active)

Both the chiral centers are retained in the product, and so reaction takes place on chiral centre.

Hence a single optically active stereoisomer is formed.
