What product is obtained when chloroform reacts with oxygen in presence of light?
A
Phosgene gas
B
Phosphine gas
C
Chlorine gas
D
Hydrogen gas
Answer
Phosgene gas
Explanation
Solution
When chloroform (CHCl) is exposed to oxygen in the presence of light, a reaction occurs that produces phosgene gas (COCl), which is highly toxic. This reaction happens due to the breakdown of chloroform molecules facilitated by light energy, which allows them to react with oxygen molecules.
