Which of the following compounds is formed when chloroform is exposed to air and light?
Options
- APhosgene.
- BPhosphine.
- CCarbon dioxide
- DCarbon tetrachloride
Correct answer
A. Phosgene.
Step-by-step solution
Chloroform ( CHCl₃ ) undergoes slow oxidation in the presence of air and light to form a highly poisonous gas called phosgene ( COCl₂ ). The chemical equation for this reaction is: 2CHCl₃ + O₂ h 2COCl₂ + 2HCl Thus, phosgene is the compound formed. Answer: Phosgene.
