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?
Show Hint
The cumene process is a very important industrial reaction to remember. The overall transformation is:
Cumene + Air \(\rightarrow\) Cumene hydroperoxide \(\xrightarrow{H^+}\) Phenol + Acetone.
It's an efficient way to produce two valuable chemicals from cheap starting materials (benzene and propene).
