The cumene process is the most important commercial method for the manufacture of phenol. Cumene is:

Identify product $C$ in the following reaction sequence:
Nitrobenzene $\xrightarrow{Sn+HCl} A$ $\xrightarrow{HNO_2, 0^{\circ}C-5^{\circ}C} B$ $\xrightarrow{H_2O, \Delta} C$

You are given benzene,conc. $H_2SO_4$ and $NaOH$. Write the equations for the preparation of phenol using these reagents.

The products $X$ and $Z$ in the following reaction sequence are:
$\text{Benzene} + CH_3-CH=CH_2$ $\xrightarrow{AlCl_3/\text{ether}, \text{Heat}} X$ $\xrightarrow{O_2/130^{\circ}C} Z$

Which one of the following reactions gives phenol as a major product?

The following equation illustrates:
$C_6H_5Cl + 2NaOH \xrightarrow{623 \ K, 300 \ atm} C_6H_5ONa + NaCl + H_2O$
