Question

On reduction with LiAlH4, which of the following compounds could yield an optically active compound?
Options
A Propanal
B Propanone
C Butanal
D Butanone
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

Butanone (CH3COCH2CH3) reduction with LiAlH4 gives 2-butanol (CH3CHOHCH2CH3), which has a chiral center at C2 and is optically active. The others give achiral products.

Hint

Which ketone reduction gives a chiral alcohol?
