The acetal in oleandrin is to be identified. The products formed by acid-catalyzed hydrolysis of the acetal are to be predicted. Concept introduction: Aldehydes or ketones on reaction with two equivalents of alcohol form acetals. Acetal formation takes place in presence of acids, commonly p -toluenesulfonicacid . This is nucleophilic addition reaction. Ethers contain only one alkoxy group on a carbon atom while acetals contain two alkoxy groups on a single carbon atom. Hemiacetals contains one alkoxy group and one hydroxyl group attached to same carbon atom.
