Explanation Question: Thealkyne undergoes complete hydrogenation to form a saturated acyl chloride

Concept: Excess ${\mathrm{H}}_2$ with $\mathrm{PD}/{\mathrm{BaSO}}_4$ reduces $\mathrm{C}\equiv \mathrm{C}$ to $\mathrm{C}-\mathrm{C}$ without affectingthe acy chloride

Solution:

${\mathrm{H}}_2,\mathrm{Pd},{\mathrm{BaSO}}_4$ is selective reducing agent which reduce acid halide in to aldehyde (Rosenmund reduction) and Alkyl in to alkene.

Final Answer: Option (A)
