Question

The halo compound of methane used as fire extinguisher under the name Pyrene is:

• A. $CHC{l}_3$
• B. $C{H}_{2}C{l}_2$
• C. $CC{l}_2{F}_2$
• D. $CC{l}_4$

Answer 1

The correct option is D $CC{l}_4$

Carbon tetrachloride $CC{l}_4$, is widely used in fire extinguishers. The liquid vaporized and extinguished the flames by inhibiting the chemical chain reaction of the combustion process.

In 1910, The Pyrene Manufacturing Company of Delaware filed a patent to use carbon tetrachloride to extinguish fires under the name $Pyrene$.

Hence, option D is correct.
