Question

Cumene $\underset{\left(ii\right)H_{2}O,H^{+}}{\stackrel{\left(i\right)O_2}{}}\left(X\right)$ and $\left(Y\right)$;

Here, $\left(X\right)$ and $\left(Y\right)$ respectively are:

• A. Toluene, propene
• B. Toluene, propylchloride
• C. Phenol, acetone
• D. Phenol, acetaldehyde

Answer 1

Answer: (C)

Phenol, acetone

To prepare phenol, cumene is first oxidized 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.

So, the correct option is 'C'.
