Given that 1,3-cyclopentadiene polymerizes slowly at room temperature to yield a polymer that has double bonds only at the ends. On heating, the polymer breaks down to regenerate 1,3-cyclopentadiene. A structure for the product is to be proposed. Concept introduction: Conjugated dienes polymerise through the 1,4 addition of one diene molecule to another diene molecule. To propose: A structure for the polymer obtained by the slow polymerization of 1,3-cyclopentadiene at room temperature and that breaks on heating to give back 1,3-cyclopentadiene is to be given.

Answer 1

Question

Definition Definition Chemical process in which one or more monomers combine to produce a very large chain-like molecule called a polymer. The functional groups present on the monomers and their steric effects are responsible for polymerization through a sequence of reactions that vary in complexity. There exists a stable covalent chemical bond between monomers that sets apart polymerization from other processes.
