Question

Cumene is oxidised in the presence of air and the product formed is treated with dilute acid

Answer 1

Cumene is made and then from cumene phenol plus Acetone is formed. To prepare phenol, cumene is first oxidized in the presence of air of cumene hydro-peroxide. Then, cumene hydroxide is treated with dilute acid to prepare phenol and acetone as by-products.

Answer 2

The correct answer is-

Explanation:

• Cumene is oxidised in the presence of air and the product formed is treated with dilute acid.
• To prepare phenol, cumene is first oxidized in the presence of air of cumene hydro-peroxide.
• Then, cumene hydroxide is treated with dilute acid to prepare phenol and acetone as by-products.
• Cumene is oxidised in presence of oxygen to form cumenehydroperxide.
• In presence of dilute aqueous acids, cumene hydroperoxide undergoes hydrolysis to form a mixture of phenol and acetone. Write the reaction for the conversion of cumene hydroperoxide to phenol and acetone.
