Question

Biodegradable polymer which can be produced from glycine and aminocaproic acid is:

Answer 1

Hint: The monomers are mentioned in the question already. Perform the polymerization reaction. Identify if the reaction is through condensation or free radical formation. Once you write the polymeric structure you can identify the name of the polymer and thus answer the question.

Complete answer:
Polymerization is a process of reacting monomer molecules together in a chemical reaction to form long polymer chains .
In chemical compounds, polymerization can occur by various types of reaction mechanisms that vary in complexity due to the functional groups present in the reactants and the steric effects that are present.
In simple polymerizations, alkenes form polymers through relatively simple free radical reactions; in contrast, reactions involving substitution at a carbonyl group require more complex synthesis due to the way in which reactants polymerize and the steric hindrance offered by neighboring groups.
The polymerization reaction between glycine and aminocaproic acid is a condensation reaction as for every mole of reactants used up, a mole of water is released. The polymerization reaction is given below:

The name of the above polymer is Nylon - 2 - nylon - 6 and it is a biodegradable polymer.

Therefore, the correct answer is option (C).

Additional information:
The two main classes of polymerisation reaction mechanisms are step-growth and chain growth polymerisation.
In step-growth polymerisation, the pairs of reactants combine at each step to form a longer polymer chain. The average molar mass increases slowly, long chains are formed only at the end of the reaction.
However, in case of chain growth polymerisation the addition of monomer to the growing chain with active centre (like free radical, cation, anion) is the chain extension step. Long chains are formed from the starting of the reaction only.

Note:
It is important to now understand the question has two parts namely, biodegradable polymer and the monomers being mentioned. So do not mark option (D) i.e. PHBV after reading biodegradable polymer. This is because the monomers mentioned above are not the monomers of PHBV and of Nylon - 2 - nylon - 6.
