Vedclass · Answer

(A) This is a $Baeyer-Villiger$ oxidation reaction.The migratory aptitude of groups is $3^\circ > 2^\circ > 1^\circ > 	ext{methyl}$.In the ketone $CH_3-CH(CH_3)-CO-CH_2-CH_3$,the groups attached to the carbonyl carbon are isopropyl $(2^\circ)$ and ethyl $(1^\circ)$.Since the isopropyl group has a higher migratory aptitude than the ethyl group,the oxygen atom inserts between the carbonyl carbon and the isopropyl group.The resulting ester is $CH_3-CH_2-COO-CH(CH_3)_2$,which is equivalent to $CH_3-CH_2-COO-CH(CH_3)-CH_3$.

In the given reaction: $CH_3-CH(CH_3)-CO-CH_2-CH_3 \xrightarrow{CF_3COOOH} [X]$ as the main product. $[X]$ will be:
