Question

Assertion `:` `1,3-` Butadiene is the monomer for natural rubber.
Reason `:` Natural rubber is formed though anionic addition polymerization.
A. If both assertion and reason are true and the reason is the correct explanation of the assertion.
B. If both assertion and reason are true but reason is not the correct explanation of the assertion.
C. If assertion is true but reason is false.
D. If assertion is false but reason is true.

Answer 1

Correct Answer - c
Natural rubber is polymer of isoprene. Thus assertion is false. Further the reason is also false because `1,3-` butadine undergoes free radical polymerisation rather than anionic.
