Question

Reaction of phenol with concentrated sulphuric acid

Answer 1

it will undergo sulfonation reaction .. where π bond will act as nucleophile

Answer 2

Answer:

Explanation:

Phenol reacts with conc. H₂SO₄ to give phenol sulhonic acids.Product of reaction depends upon condition especially temperature.

Reaction of phenol with conc.H₂SO₄ at normal temperature:-

When phenol is treated with conc. H₂SO₄ at normal temperature,o-phenol sulphonc acid is obtained.

Reaction of phenol with conc.H₂SO₄ at high temperature:—

When phenol is heated with conc.H₂SO₄,p-phenol sulphonic acid is obtained.
