Question

Explain the action of bromine in carbon disulphide (CS₂) on phenol (carbolic acid). 

OR 

Give equation of the reaction of bromine in CS₂ with phenol.

Answer 1

When phenol is stirred at a low temperature with bromine dissolved in a polar solvent such as carbon disulphide or CCl₄ at (273 K), a mixture of o-bromophenol and p-bromophenol is formed, p-bromophenol is the major product.
