Vedclass · Answer

(C) The reaction sequence is the industrial process for the preparation of phenol,known as the cumene process.$1$. Benzene reacts with propene in the presence of an acid catalyst $(H^{\oplus})$ to form cumene (isopropylbenzene) as compound $A$.$C_6H_6 + CH_3-CH=CH_2 \xrightarrow{H^{\oplus}} C_6H_5-CH(CH_3)_2$ $(A)$$2$. Cumene $(A)$ is then oxidized by $O_2$ to form cumene hydroperoxide as compound $B$.$C_6H_5-CH(CH_3)_2 + O_2 \rightarrow C_6H_5-C(CH_3)_2-O-OH$ $(B)$$3$. Cumene hydroperoxide $(B)$ undergoes acid-catalyzed rearrangement $(H^{\oplus} / \Delta)$ to yield phenol $(C)$ and acetone $(CH_3-CO-CH_3)$.$C_6H_5-C(CH_3)_2-O-OH \xrightarrow{H^{\oplus} / \Delta} C_6H_5OH + CH_3-CO-CH_3$Thus,the intermediate compound $B$ is cumene hydroperoxide.

Suppose the following reaction:
Benzene $(C_6H_6) + CH_3-CH=CH_2$ $\xrightarrow{H^{\oplus}} A$ $\xrightarrow{O_2} B$ $\xrightarrow{H^{\oplus} / \Delta} C + CH_3-CO-CH_3$
The structure of intermediate compound $B$ will be
