(C) Chloroform $(CHCl_3)$ is slowly oxidized by atmospheric oxygen in the presence of light to form an extremely poisonous gas known as phosgene $(COCl_2)$. The chemical reaction is: $2CHCl_3 + O_2 \xrightarrow{light} 2COCl_2 + 2HCl$. To prevent this oxidation,it is stored in closed,dark-coloured bottles that are completely filled to exclude air and light.
