Q. The structure of intermediate A in the following reaction is : Cumene $(C_6H_5CH(CH_3)_2) \xrightarrow{O_2} A \xrightarrow{H^+/H_2O}$ Phenol + Acetone $(CH_3COCH_3)$
A) $C_6H_5-O-CH(CH_3)_2$
B) $C_6H_5-C(CH_3)_2-O-O-H$
C) $C_6H_5-O-O-CH(CH_3)_2$
D) $C_6H_5-CH(CH_3)-CH_2-O-O-H$
Explanation
[Solution] Air oxidation of cumene gives cumene hydroperoxide, $C_6H_5C(CH_3)_2OOH$, which rearranges with acid to phenol and acetone. Answer (2).
