During the breakdown of polymers, which of the following reactions takes place?

hydrolysis

dehydration

condensation

covalent bond

Answer: Option A."Hydrolysis"

Explanation:

Polymers breaks down into monomers following hydrolysis reaction.

hydrolysis is a chemical reaction that occurs when a water molecule inserts across the bond.

In hydrolysis reactions, the polymer breaks or divide into two components one part that gains hydroxyl molecule (OH-) and the other part that gains gains a hydrogen atom (H+) due to split of water molecule.

Hence, the correct option is A.
