Question

Identify the acetal in oleandrin, and draw the products formed by acid-catalysed hydrolysis of the acetal.

Short answer

Acetal group is at C-3 carbon atom of the oleandrin.

Step-by-step solution

Protecting group

The conversion of the functional group of a compound to specify the chemoselective center of reaction is referred to as protection of the compound.

Hydrolysis

Any acetal group would hydrolyze in an acidic medium to form the corresponding carbonyl compound and alcohol.

The hydrolysis of Oleandrin is as follows,
