Vedclass · Answer

(C) The oxidation of cumene (isopropylbenzene) in air gives cumene hydroperoxide,which is compound $X$.$C_6H_5CH(CH_3)_2 + O_2 \rightarrow C_6H_5C(CH_3)_2OOH$ (Cumene hydroperoxide,$X$)Upon treatment with dilute acid,cumene hydroperoxide undergoes rearrangement to form phenol $(Y)$ and acetone $(Z)$.$C_6H_5C(CH_3)_2OOH \xrightarrow{H^+} C_6H_5OH (Y) + CH_3COCH_3 (Z)$Phenol $(Y)$ contains an acidic hydroxyl group $(-OH)$ attached to the benzene ring,which reacts with sodium metal to evolve hydrogen gas.$2C_6H_5OH + 2Na \rightarrow 2C_6H_5ONa + H_2 \uparrow$Acetone $(Z)$ is a ketone and does not contain an acidic hydrogen atom that can react with sodium metal.Therefore,$Z$ is acetone $(CH_3COCH_3)$.

Cumene on oxidation in air gives a compound,$X$. This on reaction with dilute acid gives $Y$ and $Z$. $Y$ reacts with sodium metal and not $Z$. What is $Z$ ?
