$Benzaldehyde$ can be obtained from $benzal$ chloride. Write reactions for obtaining $benzal$ chloride and then $benzaldehyde$ from it.

(N/A) Step $1$: Preparation of $benzal$ chloride from $toluene$:
$Toluene$ reacts with chlorine $(Cl_2)$ in the presence of light $(h\nu)$ at $383 \ K$ to form $benzal$ chloride (also known as $benzylidene$ chloride).
$C_6H_5CH_3 + 2Cl_2 \xrightarrow{h\nu, 383 \ K} C_6H_5CHCl_2 + 2HCl$
Step $2$: Preparation of $benzaldehyde$ from $benzal$ chloride:
$Benzal$ chloride undergoes hydrolysis with water at $373 \ K$ to yield $benzaldehyde$.
$C_6H_5CHCl_2 + H_2O \xrightarrow{373 \ K} C_6H_5CHO + 2HCl$
