What is the product of each of the following reactions?

Short Answer

Expert verified

b.

Step by step solution

01

Protection of aldehyde and ketones.

Aldehydes and ketones can be protected by using 1,2-diols in the form of an acetal. An aldehyde or ketone reacts with 1,2-diol to form a five-membered reaction. Whereas, 1,3-diol reacts with aldehyde or ketones to give a six-membered reaction.

02

Formation of the desired product

a)

Propan-2-one reacts with 1,2-diol (the provided reactant) in presence of HCl to form a cyclic acetal. Thus, the reaction is as follows:

Formation of the desired product

b)

In the provided reactant, the keto group reacts with ethane-1,2-diol in presence of HCl to form a cyclic acetal (five-membered ring). Thus, the reaction is as follows:
