Carbon Tetrachloride (CCl₄): a compound consisting of one carbon atom and four chlorine atoms Carbon tetrachloride was widely used as a raw material in many industrial uses, including the production of CFCs, and as a solvent. Solvent use ended when it was discovered to be carcinogenic. It is also used as a catalyst to deliver chlorine ions to certain processes.

Carbon Tetrachloride - CCl₄, a compound consisting of a carbon and 4 chlorines that is active in ozone depletion when the compound is broken down and releases chlorine atoms (radicals). Chlorine reacts with the ozone creating diatomic oxygen and chlorine monoxide which cycles back to chlorine radicals.
