CCl4 (carbon tetrachloride), on the other hand, does not support combustion and is used as a fire extinguishing agent and in other applications where non-flammability is required.

Among the options given, the incombustible substance is CCl4 (carbon tetrachloride).

Here’s why;

-> H2 (hydrogen gas) is highly combustible and burns with a pale blue, almost invisible flame.

-> C2H2 (acetylene) is also highly combustible and is often used as a fuel in welding torches.

-> S (sulfur) is combustible and burns with a blue flame, producing sulfur dioxide.

-> CCl4 (carbon tetrachloride), on the other hand, does not support combustion and is used as a fire extinguishing agent and in other applications where non-flammability is required.

The material doesn't get ignited an explosion of 649 °c for 5 min, will be a little shine called incombustible.

The molecular formula of carbon tetrachloride is CCl4. It is a tetrachloro derivative of methane. Its IUPAC name is tetrachloromethane and it doesn't burn.

H2 is combustable too.

Because CCl4 does not have free (delocalized) electrons as does a metal or something like graphite. Nor does CCl4 ionize in solution to form ions. It is a nonelectrolyte.
