Assertion `:` Stability of alkene is governed by hyper conjugation
Reason `:` Hyperconjugation involves delocatisation of `sigma -` electron with `sp^(2)` hybridised orbitals.

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.

Text Solution

Verified by Experts
