Which best explains the formation of polyester?
a. a condensation polymerization of a carboxylic acid and an alcohol
b. an addition polymerization of a carboxylic acid and an alcohol
c. a condensation polymerization of two alcohols
d. an addition polymerization of two alcohols

A. a condensation polymerization of a carboxylic acid and an alcohol

Explanation: Condensation polymerization is a polymerization in which two or more than two monomers combine to form a polymer along with release of simple molecules as byproduct.

Addition polymerization is a polymerization in which two or more than two monomers combine to form a single polymer.

Polyesters are compounds with functional group -COOR which is formed by combination of alcohol and carboxylic acid releasing water molecules as by products.
