Vedclass · Answer

(C) Vulcanisation is a process of treating natural rubber with sulphur or some compounds of sulphur under heat to modify its properties. In this process,sulphur forms cross-links at the reactive sites of double bonds in the rubber chain,which provides mechanical strength and elasticity to the rubber. Therefore,the Assertion is correct. However,vulcanisation is not a free radical initiated chain reaction; it is a chemical cross-linking process. Thus,the Reason is incorrect.

Assertion : In vulcanisation of rubber,sulphur cross links are introduced.
Reason : Vulcanisation is a free radical initiated chain reaction.
