$CCl_4$

Vedclass · Answer

(B) $CCl_4$ is known as pyrene. It is stable to red heat and its vapours are non-inflammable,which makes it suitable for use as a fire extinguisher. However,its use is now restricted because,in the presence of water vapor,it can form the highly poisonous phosgene gas $(COCl_2)$. The reaction is: $CCl_4 + H_2O 	o COCl_2 + 2HCl$.
