Vedclass · Answer

(C) Chloroform $(CHCl_3)$ is sensitive to light and air. When exposed to light and oxygen,it undergoes slow oxidation to form a highly poisonous gas called phosgene $(COCl_2)$. The chemical reaction is: $2CHCl_3 + O_2 \xrightarrow{	ext{light}} 2COCl_2 + 2HCl$. To prevent this oxidation,chloroform is stored in dark-colored bottles to block light and filled up to the brim to minimize contact with air.
