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 not the correct explanation of the assertion.
C. If assertion is true but reason is false.
D. If the assertion and reason both are false.

Answer 1

Correct Answer - D
The order of reactivity of carbonium ion is `1^(@) gt 2^(@) gt 3^(@)`. Carbon atom in carbonium ion is `sp^(2)` state of hybridisation. The three hybridized orbitals lie in the same plane and are involved in the formation of three `sigma` bonds with three atoms or groups while the unhybridised p-orbital remains vacant.
