The number of stereoisomers obtained by bromination of trans- 2 - butene is

A

1

B

2

C

3

D

4

Text Solution

Verified by Experts

The correct Answer is:
A
The addition of `Br_2` across a double bond involves the formation of a bromonium ion intermediate followed by the anti addition of `Br^-` . For trans-2-butene, the reaction proceeds so as to form meso-2, 3-dibromobutane.

Thus, only, one stereoisomer is obtained.
