Text Solution

Verified by Experts

The correct Answer is:
B
`"CCl"_4` is stable to red heat. Its vapours are highly noninflammable i.e. do not catch fire. It is because of this property `"CCl"_4` is used as a fire extinguisher. But now a days its use as a fire extinguisher is restricted because with water vapours, it forms highly poisonous phosgene gas.
`"CCl"_4+H_2O rarr underset("Phosgene")(COCl_2)+2HCl`
