In one to two sentences, explain why structural formulas are good for depicting polymers

Structural formulas of polymers show the actual arrangement of atoms within the polymer. This helps us to explain some of the observed properties of the polymer.

A polymer is composed of monomers. Monomers are small molecules which could link together to form a larger molecule.

There are three kinds of formulas that could be used to represent a chemical substance;

Th structural formula shows the actual arrangement of atoms in the polymer. When we have an idea of the actual arrangement of atoms in the polymer, certain properties of the polymer substance become easily understandable.
