  1. A 1
  2. B 2
  3. C 3
  4. D 4
Verified Solution

Answer & Solution

Correct Answer

(B) 2

Step-by-step Solution

Detailed explanation




where \(C^{*}=\) asymmetric \(C\) atom
It is a symmetrical molecule, so the number of optically active stereomers \(=2^{\mathrm{n}-1}\)
( \(\mathrm{n}=\) number of asymmetric \(C\) atom)
\(=2^{2-1}\)
\(=2^{1}=2\)
