Question

When C$_6$H$_5$COCOC$_6$H$_5$ is reduced with LiAlH$_4$, the product formed has __________ stereoisomers.

• A. 2
• B. 3
• C. 4
• D. 6
• E. 8

Hint:

When a molecule has $n$ identical chiral centers, the number of stereoisomers is reduced because of the meso form. For $n=2$, total isomers = $2^{(n-1)} + 2^{(n/2 - 1)} = 2 + 1 = 3$.

Answer 1

The Correct Option is B
