Question

What is electrophilic aromatic substitution?

Answer 1

Substitution of an aromatic molecule, typically benzene, `C_6H_6`.

Explanation:

`C_6H_6 + Br_2 rarr C_6H_5Br + HBr......`

This is usually catalyzed by some Lewis-acid....Because `HBr` is eliminated, the aromaticity of the ring is retained.
