Question

i) What is the role of sulphur in the vulcanization of rubber?
ii) Identify the monomers in the following polymer:


iii)Arrange the following polymers in the increasing order of their intermolecular forces:
Terylene, polythene, Neoprene

Answer
i) when we vulcanize rubber by using sulphur, the sulphur reacts with double bond chains and forms disulphide (or similar) bonds and rubber gets stiffened.

ii) The monomer of PET are Ethylene glycol and Terephthalic acid :

iii) Neoprene <  Polythene < Terylene
