What is Carbocation

A carbocation is a molecule in which a carbon atom bears three bonds and a positive charge. It is an electron-deficient species with an incomplete octet and is stabilized by adding a nucleophile, forming a new covalent bond. Carbocations are very reactive and unstable due to their incomplete octet.

They are classified into primary, secondary, and tertiary carbocations based on the number of carbon atoms bonded to the positively charged carbon. Carbocation rearrangements are common in organic chemistry reactions and are defined as the movement of a carbocation from one carbon atom to another.

Carbocation Definition

Carbocations are electron-deficient species with an incomplete octet and a positive charge on the carbon atom.
