Detailed Solution
Rate of Nucleophilic Addition α electrophilicity of carbonyl carbonReactivity of Ketones < AldehydesDue +I effect and steric hindrance Ketones are less reactive+I effect of two alkyl groups decreases the electrophilicity of carbon. Presence two alkyl groups on carbonyl carbon increases the steric hindrance.∴ Most reactive unsubstituted carbonyl compound towards nucleophilic addition is HCHO.
