Vedclass · Answer

(A) The Assertion is True because both aldehydes $(R-CHO)$ and acid derivatives ($R-CO-Z$,where $Z = -Cl, -OR, -NH_2$) contain the carbonyl group $(>C=O)$. The Reason is also True. Aldehydes undergo nucleophilic addition reactions because the carbonyl carbon is electrophilic and the addition product is stable. However,in acid derivatives,the lone pair on the substituent $(Z)$ participates in resonance with the carbonyl group,which reduces the electrophilicity of the carbonyl carbon. Consequently,they undergo nucleophilic acyl substitution rather than simple nucleophilic addition. Thus,the Reason correctly explains why acid derivatives do not exhibit the same nucleophilic addition reactions as aldehydes.

Assertion $: - >C=O$ group is present in both aldehydes and acid derivatives.
Reason $: -$ Aldehydes give nucleophilic addition across $>C=O$ bond but acid derivatives do not exhibit such reactions.
