TestHub · Accepted Answer

Acetal is form from the reaction of aldehyde with excess of $M e O H$

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.
