Short Answer

Expert verified

Any chemical compound used in the modification of the reacting compound in order to specify the site of chemo-selectivity is known as the 鈥榩rotecting groups.鈥�

Acetals are used as the protecting group of carbonyl compounds.

Step by step solution

01

Protecting group

Any chemical compound used in the modification of the reacting compound in order to specify the site of chemo-selectivity is known as the 鈥榩rotecting groups.鈥�

Acetals are used as the protecting group of carbonyl compounds.

02

Acetal group
