A. What is the role of t-butyl peroxide in the polymerization of ethane?

B. Identify the monomers in the following polymer:

C. Arrange the following polymers in the increasing order of their intermolecular forces:

Polystryrene, Terylene, Buna-S

Answer :

(a) The decomposition of peroxides like t-butyl peroxide or benzoyl peroxide produces free radicals, which are used in the polymerization of ethene to initiate the chain reaction.

(b) The abovementioned polymer is Nylon 6,6. Its monomers are adipic acid (HOOC(CH2)4COOH) and hexamethylenediamine (H2N(CH2)6NH2)

(c) The increasing order of intermolecular forces of the given polymers is:

Terylene > Polystyrene > Buna-S
