The answer of your question is "Phosgene gas (CHCl2)"
Phosgene gas is produced when the chloroform is exposed to air or open air. The air exposure causes the oxygen interaction and oxidation of chloroform. Phosgene is really a dangerous gas which cause fatality even only at 50ppm exposure.And if this exposure increased to 500 ppm this gas may cause immediate effect leading to the death.Person exposed to this gas initially faced to symptoms but death can occur upto 24 hours later.

The correct answer is - Phosgene (COCl₂)
In the presence of light, Chloroform (CHCl₃) is oxidized in air and it decomposes to form a poisonous gas called as Phosgene gas (COCl₂).
CHCl₃ + ¹/₂ O₂ → COCl₂ + HCl. This reaction takes place in the presence of sunlight.
Therefore, it is always advised to store chloroform in dark colored bottles. Before using chloroform as an anesthetic, it is usually tested with AgNO₃. Poisonous chloroform gives a white precipitate with AgNO₃.
