Answer :
Structure of acetal is in Word document below.
Acetal is produced when one molecule of aldehyde (in this reaction ethanal) and two molecules of alcohols (in this reaction ethanol) react. Hemiacetal is produced when one molecule of aldehyde and one molecule of alcohol react. Acetals are stable compared to hemiacetals.
Acetal is produced when one molecule of aldehyde (in this reaction ethanal) and two molecules of alcohols (in this reaction ethanol) react. Hemiacetal is produced when one molecule of aldehyde and one molecule of alcohol react. Acetals are stable compared to hemiacetals.
Explanation:
Acetals are geminal diethers derivatives of aldehyde formed by the addition to equivalent molecules of an alcohol and removal of water.
When ethanol is added to the ethanal in acidic medium:
Ethanal + Ethanol → Hemiacetal
Hemiacetal + Ethanol → Acetal
Acetal produced when ethanol is added to ethanal are given in the image attached.
