Note : In the following questions a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices.

Assertion : Olefinic monomers undergo addition polymerisation.

Reason : Polymerisation of vinylchloride is initiated by peroxides/ persulphates.

Olefin also called alkene, compound made up of hydrogen and carbon that contains one or more pairs of carbon atoms linked by a double bond. Olefins are examples of unsaturated hydrocarbon (compounds that contain only hydrogen and carbon and at least one double or triple bond).

The olefins monomers undergo the addition polymerization, for example, ethene undergoes addition polymerization to give polyethylene.

Polymerization of vinyl chloride is initiated in the presence of peroxides.

Thus, both the assertion and the reason are correct but the reason is not the correct explanation of the assertion.
