Answer 2

Answer:

Explanation:Preparation of phenol from cumene \rightarrow→To prepare phenol, cumene is first oxidised in the presence of air to cumene hydroperoxide.

\underset{\left( \text{Isoprophyl benzene} \right)}{\text{Cumene}} \xrightarrow[]{{O}_{2}} \text{Cumene hydroperoxide}  

(Isoprophyl benzene)

Cumene

Cumene hydroperoxide

Now, cumene hydroperoxide is treated with dilute acid to prepare phenol and acetone as by-products.

\text{Cumene hydroperoxide} \xrightarrow[323-363 \; K]{{H}^{+}} \text{Phenol} + \text{Acetone}Cumene hydroperoxide  

H  

+

 

323−363K

​  

Phenol+Acetone

By this method, acetone is obtained in large quantities.
