NEET levelSingle correct optionDifficulty 1 of 3hx185

Chloroform is slowly oxidised by air in the presence of light to form a highly poisonous gas. The gas is

Aphosgene, $COCl X_{2}$
Bcarbon tetrachloride, $CCl X_{4}$
Cdichloromethane, $CH X_{2} Cl X_{2}$
Dcarbon monoxide, $CO$ only

Answer: A

Light and air oxidise

CHCl X_{3}

to carbonyl chloride,

COCl X_{2}

(phosgene), which is very toxic. Chloroform is therefore stored in dark bottles filled to the brim.
