Answer»

COCl_2ANSWER: Phosgene gas is formed when chloroform is exposed in AIR and sunlight.

Explanation: When Chloroform is exposed to air, it UNDERGOES oxidation releasing a toxic gas that is Phosgene gas and Hydrochloric acid.

Reaction of oxidation of chloroform is:

2CHCl_3(l)+O_2(g)\rightarrow 2COCl_2(g)+2HCl(g)

As chloroform toxic gas when it is exposed to air and sunlight, therefore it is KEPT in dark BOTTLES to prevent any oxidation process.
