Vedclass · Answer

(D) The given acetal is a cyclic ketal formed from a ketone and a diol. By analyzing the structure of the acetal,we can identify the ketone and the diol used in its synthesis. The acetal contains a cyclopentane ring attached to the ketal carbon,which indicates that the starting ketone is cyclopentanone. The ketal part is a six-membered ring containing two oxygen atoms,which is derived from $2,2-$dimethylpropane$-1,3-$diol (neopentyl glycol). The reaction is: $	ext{Cyclopentanone} + 	ext{2,2-dimethylpropane-1,3-diol} \xrightarrow{H^+, \Delta} 	ext{Acetal} + H_2O$. Thus,the correct pair of reactants is cyclopentanone and $2,2-$dimethylpropane$-1,3-$diol.
