`C Cl_(4)` is a well known fire extinguisher. However after using it to extinguish fire the room should be well ventilated. This is because:

A

it is flammable at high temperature

B

it is toxic

C

it produces phosgene by reaction with water vapour at higher temperature

D

it is corrosive

Text Solution

Verified by Experts

The correct Answer is:
C
`"CCl"_(4)` at high temperature reacts with water to give phosgene.
`"CCl"_(4)+H_(2)O overset(500^(@)C)rarr underset("Phosgene")(COCl_(2))+2HCl`
Phosgene is highly poisonous, so after the use of pyrene `("CCl"_(4))`, to extinguish fire, the room should be ventilated.
