In the following reaction Aldehyde + Alcohol → HCl Acetal A l d e h y d e A l c o h o l HCHO t - BuOH CH 3 CHO MeOH The best combination is:, HCHO and MeOH, CH 3 CHO and t - BuOH, CH 3 CHO and MeOH, HCHO and t- BuOH

MARKS App · Accepted Answer

Formation of an acetal occurs when the hydroxyl group of a hemiacetal becomes protonated and is lost as water. The carbocation that is produced is then rapidly attacked by a molecule of alcohol. Loss of the proton from the attached alcohol gives the acetal.
