Isopentane can form four structurally isomeric mono bromo derivatives. How many of them are cally active?

A

1

B

2

C

3

D

4

Text Solution

Verified by Experts

The correct Answer is:
B
Mono bromo derivatives of ISO pentane are
1) `CH_3 - oversetunderset(|)(CH_3)(C) H - CH_2 - CH_2 - Br`

Among (4) isomers two are optically active due to the presence of chiral centre
