Q. In Dow's process for the manufacture of phenol, $PhCl$ is fused with $NaOH$ at elevated temperature under pressure.
$PhCl \xrightarrow[623\, K , 300\text{atm }]{NaOH}[$ Intermediate $] \xrightarrow{ H _{2} O }\underset{(A)}{\text{Phenol}} + \underset{\text{Side product}}{( B + C )}$ Which of the following statements are correct:

Haloalkanes and Haloarenes

Solution:

Correct answer is (a) Phenol is formed via the formation of benzyne intermediate.Correct answer is (b) $p$-Phenyl phenol is also formed as a by-product.Correct answer is (c) Diphenylether is also formed as a by-product.
