Assertion (A): Olefinic monomers undergo addition polymerisation.
Reason (R): Polymerisation of vinylchloride is initiated by peroxides/ persulphates.
Assertion (A): Olefinic monomers undergo addition polymerisation.
Reason (R): Polymerisation of vinylchloride is initiated by peroxides/ persulphates.
The correct option is D Both the assertion and the reason are correct statements, but the reason is not the correct explanation of the assertion
Assertion:
Olefin, also called alkene, is a compound made up of hydrogen and carbon that contains one or more pairs of carbon atoms linked by a double bond.
In addition polymerisation, the molecules of the same monomer or different monomers add together on a large scale to form a polymer.
The double bonds of monomers break, and the extra valency of the double-bonded carbon gets satisfied by joining with another monomer.
So, olefin monomers undergo addition polymerisation.
Hence, the assertion is a correct statement.
Reason:
Polyvinyl chloride is produced by the addition polymerisation of chloroethene (vinyl chloride) monomers. This polymerisation reaction proceeds by a free radical mechanism where the polymerisation process is initiated by free radicals like peroxides or ionic species like persulphates. But this is not the reason why olefins undergo addition polymerisation.
Hence, the reason is a correct statement.
Both the assertion and the reason are correct statements, but the reason is not the correct explanation for the assertion.
So, option (a) is the correct answer.
