Which of the following is the correct represetation for intermediate of nucleophilic addition reaction to the given carbonyl compound (A) ?

Options

A.
B.
C.
D.

Answer

A, B

Explanation

Since, carbonyl compound is a planar molecule hence two orientation of molecule regarding attack of nucleophile is possible as follows

Since, the product contains a chiral carbon, therefore, attack of nuclephile can occur either from front side attack or rear side attack giving enantiomeric products. Hence. (a) and (b)
