Q. Consider the following reaction sequence-
$CH _{3}- C \equiv C - CH _{3} \frac{ Pd - BaSO _{4}}{ H _{2}} A \stackrel{ Br _{2}}{\longrightarrow } B$
A & B, respectively, are

Hydrocarbons

Solution:

With Lindlar’s catalyst, cis-alkene is formed which undergoes anti addition with $Br_2$ to give Racemic mixture.
