An alkene on reaction with `Br_(2)//C CI_(4)` produces the following products:

and its enantiomer in equal amounts. The alkene is

A

trans-pent`-2-`ene

B

pent`-1-`ene

C

cis-pent`-2-`ene

D

`2-`methylbut`-2-`en

Text Solution

Verified by Experts

The correct Answer is:
C
Addition of halogens to alkenes is an anti-addition. Thus cis-alkene yields a racemic mixture while trans-alkene yields a meso compound.
