Acetal

Answer

Acetal: In acetal two alkoxy groups are present on the terminal carbon atom. One bond is connected to an alkyl group and other is connected to a hydrogen atom.

On reaction of aldehyde and monohydric alcohol in the presence of dry HCl gas, hemiacetals are produced which on further reaction with one more molecule of alcohol yield acetal.
