Vedclass · Answer

(C) The given reaction is the industrial preparation of phenol from cumene (isopropylbenzene).$1$. Cumene reacts with oxygen $(O_2)$ to form cumene hydroperoxide $(A)$: $C_6H_5-CH(CH_3)_2 + O_2 \rightarrow C_6H_5-C(CH_3)_2-O-OH$$2$. Cumene hydroperoxide $(A)$ on treatment with dilute acid $(H_3O^+)$ undergoes rearrangement to produce phenol $(B)$ and acetone $(C)$:$C_6H_5-C(CH_3)_2-O-OH \xrightarrow{H_3O^+} C_6H_5OH + (CH_3)_2CO$Thus,$A$ is cumene hydroperoxide,$B$ is phenol,and $C$ is acetone. The correct option is $C$.

What are $A$,$B$ and $C$ in the following reactions?
$\text{Cumene}$ $\xrightarrow{O_2} A$ $\xrightarrow{H_3O^{+}} B + C$
