Which one of the following compounds is most reactive towards nucleoph – InterviewSolution

1.	Which one of the following compounds is most reactive towards nucleophilic addition
Answer» `CH_(3)CHO` `PhCOCH_(3)` `PhCOPh` `CH_(3)COCH_(3)` Solution :In nucleophilic addition reaction of carbonyl compounds order of reactivity is The lower reactivity of ketones over aldehydes is due to `+I` effect of the alkyl group. The aromatic aldehydes and ketones are LESS reactive than their ALIPHATIC analogues. This is due to the `+R` effect of the benzene ring. From the above information, it is clear that INCREASING order of the nucleophilic addition reaction in the following compound will be, `PhCOPh lt PhCOCH_(3) lt CH_(3)COCH_(3) lt CH_(3)CHO`
