Organic reactions take place through the formations of reactive carbon intermediates formed by cleavage of covalent bonds. Formation of these intermediates depends upon the dissociation energies of covalent bonds.
1. Which is not the intermediate formed by cleavage of covalent bonds.

A

Free radical

B

Carbocation

C

Carbonium ion

D

Carbanion.

Text Solution

Verified by Experts

The correct Answer is:
C
Carbonium ion `CH_(5)^(+)` is formed by protonation of an alkane `CH_(4)+H^(+) rarr CH_(5)^(+)`.
