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.
