Vedclass · Answer

(D) The reactivity of carbonyl compounds towards nucleophilic addition depends on steric and electronic factors. Ketones are generally less reactive than aldehydes because: $1.$ The $+I$ effect of two alkyl groups in ketones reduces the positive charge (electrophilicity) on the carbonyl carbon more than the single alkyl group in aldehydes. $2.$ The presence of two bulky alkyl groups in ketones creates more steric hindrance for the attacking nucleophile. Among the given options,$CH_3COC_2H_5$ (butanone) is a ketone with the largest alkyl groups,making it the least reactive.
