The correct structure of the product A formed in the reaction:
A -
B -
C -
D -

Explanation

Pd/C with 1 atm H₂ reduces C=C, not C=O.

Detailed Solution


Cyclohex-2-en-1-one $\xrightarrow{H_2\ (1\ atm),\ Pd/C,\ ethanol}$ cyclohexanone
Only the C=C is reduced under these mild conditions; the C=O remains. So A is cyclohexanone.
