Assertion (A) : Natural rubber is a linear polymer of isoprene called cis-polyisoprene with elastic properties.

Reason (R) : The cis- polyisoprene molecules consist of various chains  held together by strong polar interactions with coiled structure.

In the light of the above statement, choose the correct one from the options given below:

Option: 1

Both (A) and (R) are true and (R) is the correct explanation of (A).


Option: 2

Both (A) and (R) are true but (R) is not the correct explanation of (A).


Option: 3

(A) is true but (R) is false.


Option: 4

(A) is false but (R) is true.


Answers (1)

Assertion is correct but Reason says that cis-polyisoprene molecules consists of various chains held together by strong polar interactions with coiled structure, which is incorrect.

The chains are held together by weak Vander Waal's interactions.

Hence ,Option (3) is Correct.
