Product of the given reaction is:

Answer & explanation
Correct answer: option 2
The correct answer is option 2. \(RCH_2COOCH_2R'\).
The reaction is known as Baeyer-Villiger Oxidation. The Baeyer-Villiger Oxidation is the oxidative cleavage of a carbon-carbon bond adjacent to a carbonyl, which converts ketones to esters and cyclic ketones to lactones. The Baeyer-Villiger can be carried out with peracids, such as trifluoroperacetic acid (TFPAA), perbenzoic acid (PBA), peracetic acid (PAA) or with hydrogen peroxide and a Lewis acid.
