What is the major organic product formed when ethyl methyl ketone is treated with peracetic acid?

Step-by-step solution

The reaction of a ketone with a peroxy acid (such as peracetic acid) to form an ester is known as the Baeyer-Villiger oxidation. In this reaction, an oxygen atom is inserted between the carbonyl carbon and one of the adjacent alkyl groups. The regioselectivity of the insertion is determined by the migratory aptitude of the alkyl groups, which follows the order: 3^ > 2^ > 1^ > methyl . The given substrate is ethyl methyl ketone ( CH₃-CO-CH₂CH₃ ). The two groups attached to the carbonyl carbon are an ethyl group ( 1^
