Question

Draw the products of the complete hydrolysis of a ketal. Draw all products of the reaction.

Answer 1

Concepts and reason

The concept used is to draw the products of the hydrolysis of a ketal.

Fundamentals

A compound that contains two alkoxy group bonded to the same carbon atom is a ketal. The general structure of ketal is R₂C(OR’)₂, here R is alkyl or aryl.

A compound that contains one alkoxy group and one hydroxyl group bonded to the same carbon atom is a hemiacetal.

Protection of carbonyl compounds produces acetals and ketals.

Ketals can be hydrolyzed by the aqueous acidic medium.

Hydrolysis of ketals in the presence of acidic medium produces hemi-acetal. The reaction is as follows:

Hydrolysis of hemiacetal in the presence of acidic medium produces carbonyl compound and corresponding alcohol. The reactions are as follows:

Ans:

The reaction showing all products is as follows:
