Vedclass · Answer

(C) In the first step,chloroform $(CHCl_3)$ is oxidized by air in the presence of light to form phosgene $(COCl_2)$: $2CHCl_3 + O_2 \xrightarrow{hv} 2COCl_2 + 2HCl$ In the second step,phosgene $(x)$ reacts with excess benzene in the presence of anhydrous $AlCl_3$ (Friedel-Crafts acylation) to form benzophenone $(y)$: $COCl_2 + 2C_6H_6 \xrightarrow{Anhy. AlCl_3} C_6H_5-CO-C_6H_5 + 2HCl$

In the reaction sequence $CHCl_3$ $\xrightarrow{Air/hv} x$ $\xrightarrow[Excess]{C_6H_6 / Anhy. AlCl_3} y$,$y$ will be
