Question

Draw the structures of the aldehydes or ketones and alcohols formed when these acetals are treated with aqueous acid and hydrolyzed.

Answer 1

Answer #1

(a) Name and structure of the following an acetal is

The 2, 2-diethyl-1, 3-dioxolane molecule undergoes acid catalyzed hydrolysis gives 3-pentanone and 1, 2-ethanediol as a products.

The products are shown in the following reaction:

(b) Name and structure of the following an acetal is

The acid catalyzed hydrolysis of 1-(dimethoxymethyl)-2-methoxybenzene results in the formation of 2-methoxybenzaldehyde and methanol.

The products are shown in the following reaction:

(c) Name and structure of the following an acetal is

The acid catalyzed hydrolysis of 1, 1-dimethoxycyclohexane results in the formation of cyclohexanone and methanol.

The products are shown in the following reaction:

(d) Name and structure of the following an acetal is
