Vedclass · Answer

(B) The given reactant is a diester with a ketal group. Upon treatment with $H_3O^{\oplus}$ and heating,the following steps occur:$1$. Hydrolysis of the two ester groups $(-CO_2Et)$ to carboxylic acid groups $(-COOH)$ and hydrolysis of the ketal group ($-OMe$ groups) to a ketone group $(=O)$.$2$. The resulting intermediate is a $\beta$-keto dicarboxylic acid.$3$. $\beta$-keto acids and gem-dicarboxylic acids are unstable upon heating and undergo decarboxylation (loss of $CO_2$).$4$. The molecule loses two molecules of $CO_2$ and one molecule of $H_2O$ to yield cyclohexanone as the final product $(A)$.

The product $(A)$ obtained is:
