Vedclass · Answer

(B) The reaction of a ketone with ethylene glycol in the presence of an acid catalyst $(H^+)$ is a standard method for the protection of the carbonyl group as a cyclic acetal. In the given molecule,ethyl acetoacetate,there are two carbonyl groups: a ketone and an ester. Ketones are more reactive towards nucleophilic addition than esters. Therefore,the ethylene glycol selectively reacts with the ketone group to form a cyclic acetal,while the ester group remains unaffected. The product $A$ is the cyclic acetal of ethyl acetoacetate.

The product $A$ in the above reaction is
