Carbon tetrachloride, also known by many other names (such as carbon tet for short and tetrachloromethane, also recognised by the IUPAC), is a chemical compound with the chemical formula CCl 4. It is a non-flammable, dense, colourless liquid with a "sweet" chloroform-like odour that can be detected at low levels.

Carbon dioxide (CO 2) has two polar C=O bonds, but the geometry of CO 2 is linear so that the two bond dipole moments cancel and there is no net molecular dipole moment; the molecule is nonpolar. In methane , the bonds are arranged symmetrically (in a tetrahedral arrangement) so there is no overall dipole.
A solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid. Water is a solvent for polar molecules, and the most common solvent used by living things; all the ions and proteins in a cell are dissolved in water within the cell. Major uses of solvents are in paints, paint removers, inks, and dry cleaning. [2]
The output of these processes is a mixture of chloromethane, dichloromethane, chloroform, and carbon tetrachloride as well as hydrogen chloride as a byproduct. These compounds are separated by distillation .
Carbon tetrachloride (CCl 4) can turn into phosgene when exposed to heat in air. This was a problem as carbon tetrachloride is an effective fire suppressant and was formerly in widespread use in fire extinguishers. [15] There are reports of fatalities caused by its use to fight fires in confined spaces. [16]
The carbon atom lies at or near the apex of a square pyramid with the other four groups at the corners. [ 7 ] [ 8 ] The simplest examples of organic molecules displaying inverted tetrahedral geometry are the smallest propellanes , such as [1.1.1]propellane ; or more generally the paddlanes , [ 9 ] and pyramidane ([3.3.3.3]fenestrane).
