Vedclass · Answer

(A) The reactivity of carbonyl compounds towards nucleophilic addition depends on the magnitude of the positive charge on the carbonyl carbon. $1$. Aldehydes are more reactive than ketones due to less steric hindrance and lower electronic effect. Thus,$(i), (ii), (iv)$ are more reactive than $(iii)$. $2$. Electron-withdrawing groups $(EWG)$ increase reactivity by increasing the positive charge on the carbonyl carbon,while electron-donating groups $(EDG)$ decrease it. $3$. The $-NO_2$ group in $(ii)$ is a strong $EWG$,making it the most reactive. $4$. The $-CH_3$ group in $(iv)$ is an $EDG$,making it less reactive than benzaldehyde $(i)$. $5$. Acetophenone $(iii)$ is a ketone and has an electron-donating phenyl group,making it the least reactive. Therefore,the order is $(ii) > (i) > (iv) > (iii)$.

Arrange the following carbonyl compounds in decreasing order of their reactivity in nucleophilic addition reaction:
$(i)$ Benzaldehyde
(ii) $p$-Nitrobenzaldehyde
(iii) Acetophenone
(iv) $p$-Methylbenzaldehyde
