Question

What polyamide is formed from each monomer or pair of monomers?

(a.)

(b.)

(c.)

Short answer

Answer

(a.)First polymer

(b.)Second polymer

(c.)Third polymer

Step-by-step solution

Polyamides

Polyamides are polymers made from amino group linkages and carboxylic acid molecule. It also consist of synthetic fibres, eg. Nylon.

Formation of the first polymer

The groups present at the end of the monomer will become NH and it joins the alkyl group. The reaction is shown below.

Formation of first polymer

Formation of the second polymer

The given monomer reacts with water. This will result in the opening of the ring. The oxygen atom and the NH group remain unchanged. The reaction is shown below.

Formation of the second polymer

Formation of the third polymer

NH₂groups present at the end of the monomer will become NH and it joins the alkyl group. The reaction is shown below.

Formation of the third polymer
