(Solution) - Aldehydes and ketones undergo acid catalyzed reaction with alcoh -(2025 Original AI-Free Solution)

Paper Details

Aldehydes and ketones undergo acid-catalyzed reaction with alcohols to yield hemiacetals, compounds that have one alcohol-like oxygen and one ether-like oxygen bonded to the same carbon. Further reaction of a hemiacetal with alcohol then yields an acetal, a compound that has two ether-like oxygen?s bonded to the same carbon.
(a) Show the structures of the hemiacetal and acetal you would obtain by reaction of Cyclohexanone with ethanol.
(b) Propose a mechanism for the conversion of a hemiacetal into anacetal.
