Answer

Step by step solution

01

Polymer

Polymers are formed by the addition/condensation of monomer units that form large/long-chain molecules.Polymers are also said to be macromolecules i.e. higher molecular mass.

02

Structure of polymer

In the above question, there are 4 polymers in chain form. We have to represent them in shorthand form.

The monomer of this polymer is ethyl acetoacetate.

Structure of ethyl acetoacetate polymer

The monomer of this polymer is amino cyclohexane carboxylic acid.

Structure of amino cyclohexane carboxylic acid polymer

The monomer of this polymer is 2, 2-dimethyl butane carboxyl.

Structure of 2, 2-dimethyl butane carboxyl polymer

The monomer of this polymer is 1, 3-propandiol.

Structure of 1, 3-propandiol polymer
