Question

Assertion: The order of reactivity of carbonium ions is `1^(@)gt2^(@)gt3^(@)`.
Reason: Carbon atom in carbonium ions is in `sp^(3)` state of hybridisation.
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 and the reason is the correct explanations 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
The order of reactivity of carbonium ions is `1^(@)gt2^(@)gt3^(@)`. Carbon atom in carbonium ion is `sp^(2)` state of hybridisation. The three hybridized of there `sigma` bonds with three atoms involved in the formation of three `sigma` bonds with three atoms or group while the unhybridised `p`-orbital remains vacant.
