Question

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

Answer 1

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