Nucleophilic Addition reaction

Which of the following carbonyl compound is most reactive towards nucleophilic addition reactions


Rate of Nucleophilic Addition α  electrophilicity of carbonyl carbon

Reactivity of Ketones < Aldehydes

Due +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.
