What is the hybridisation of carbon atom in C–X bond of aryl halides

The hybridisation of the carbon atom in the C-X bond of aryl halides is sp2.

Here's the step-by-step explanation:

1. Aryl halides are a type of organic compound in which a halogen atom is directly bonded to a carbon atom of an aromatic ring. The most common example of an aryl halide is chlorobenzene (C6H5Cl), where the halogen (chlorine) is bonded to a carbon atom of the benzene ring.

2. The carbon atoms in an aromatic ring such as benzene are sp2 hybridised. This means they use three sp2 hybrid orbitals to form sigma bonds with two other carbon atoms and one hydrogen atom, and the remaining unhybridised p orbital to form a pi bond.

3. When a halogen atom replaces a hydrogen atom in the aromatic ring, it forms a sigma bond with the carbon atom using one of the carbon's sp2 hybrid orbitals. Therefore, the hybridisation of the carbon atom in the C-X bond of aryl halides remains sp2.
