Question

The number of chiral centres present in the above compound is

• A. \N
• B. 1
• C. 2

Answer 1

The correct option is A \N

Chiral centre is the one which has four different valancy or groups.
Carbon 1 and 3 are not chiral because of two valancies are same except $Cl$ and $H$.
Carbon 2 and 4 are not chiral beacuse they have two $H$ and other group two $CHCl$ group thus they are also not chiral centre.
