Cumene $$\underset {(ii) H_{2}O, H^{+}}{\xrightarrow {(i) O_{2}}} (X)$$ and $$(Y)$$; Here, $$(X)$$ and $$(Y)$$ respectively are :

AToluene, propene
BToluene, propylchloride
CPhenol, acetone
Correct Answer
DPhenol, acetaldehyde

Solution

the preparation of phenol from cumene. To prepare phenol, cumene is first oxidised in the presence of air to cumene hydroperoxide. Now, cumene hydroperoxide is treated with dilute acid to prepare phenol and acetone as by-products. By this method, acetone is obtained in large quantities.
