Vedclass · Answer

(B) The reaction involves the acid-catalyzed condensation of an aldehyde (pivalaldehyde) with an $\alpha$-hydroxy acid ($2$-hydroxyisobutyric acid). $1$. The carbonyl oxygen of the aldehyde gets protonated by $H^+$. $2$. The hydroxyl group of the $\alpha$-hydroxy acid acts as a nucleophile and attacks the electrophilic carbonyl carbon of the protonated aldehyde. $3$. Subsequently,the carboxylic acid group of the $\alpha$-hydroxy acid reacts with the newly formed hemiacetal hydroxyl group to form a cyclic acetal structure. $4$. The final product is a cyclic acetal containing a carbonyl group,which corresponds to the structure shown in option $B$.
