Question

Predict the products of the following reactions:

Short answer

The product will be

Step-by-step solution

Definition of Lindlar’s catalyst and  H2,Pd/C

Lindlar’s catalyst – This catalyst only reduces the alkyne into alkene. This catalyst does not reduces alkene

${\mathbf{H}}_{\mathbf{2}}\mathbf{,}\mathbf{Pd}\mathbf{/}\mathbf{C}$ - This catalyst reduces both alkyne and alkene converts into alkane.

Formation of product

Alkyne and alkene which are present in the compound has been reduced by ${\text{H}}_2\text{,Pd/C}$

But Lindlar’s catalyst reduces only triple bond present in the compound.
