Carbon+Tetrachloride

Both carbon tetrachloride and tetrachloromethane are acceptable names under IUPAC nomenclature.
 * Carbon tetrachloride**, also known by many other names (the most notable being **carbon tet** in the cleaning industry, and as Halon or Freon in __HVAC__; see Table for others) is the organic compound with the formula CCl4. It was formerly widely used in fire extinguishers, as a precursor to refrigerants , and as a cleaning agent . It is a colourless liquid with a "sweet" smell that can be detected at low levels.

In the carbon tetrachloride molecule, four chlorine atoms are positioned symmetrically as corners in a tetrahedral configuration joined to a central carbon atom by single covalent bonds. Because of this symmetrical geometry, CCl4 is non-polar

In the 20th century, carbon tetrachloride was widely used as a dry cleaning solvent, as a refrigerant, and in lava lamps. [|[5]]
