Vedclass · Answer

(D) $1$. The first step involves the hydrogenation of the alkene double bond in the cyclohexenone ring using Wilkinson's catalyst,$(Ph_3P)_3RhCl$. This catalyst is selective for the hydrogenation of alkenes without affecting other functional groups like the ester or the nitro group. Thus,$(A)$ is the saturated ester.$2$. The second step is the alkaline hydrolysis (saponification) of the ester $(A)$ using $0.1 \ M \ NaOH$ in aqueous methanol. This reaction cleaves the ester bond to produce the carboxylate salt and the corresponding alcohol.$3$. The carboxylate salt formed is the $p$-nitrobenzoate ion,which is product $(B)$. The other product $(C)$ is the alcohol,which contains no nitrogen.

The product $(B)$ of the reaction is:
