Addition of h2 to 2-pentyne in the presence of the lindlar's catalyst will produce:

Answer : When addition of to 2-pentyne in the presence of the Lindlar's catalyst will produce cis-2-pentene.

Explanation :

Role of Lindlar's catalyst :

It is a deactivated catalyst having in lead acetate poisoned with small amount of quinoline and is used for the reduction of alkynes to cis-alkenes.

When addition of to 2-pentyne in the presence of the Lindlar's catalyst will produce cis-2-pentene.

The chemical reaction is shown below.
