 Custom Search Lewis Dot of Tetrachloromethane (aka Carbon Tetrachloride) CCl4 From-http://en.wikipedia.org/wiki/Carbon_tetrachloride 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. Methane gas has the same structure, making carbon tetrachloride a halomethane. As a solvent, it is well suited to dissolving other non-polar compounds, fats and oils. It can also dissolve iodine. It is somewhat volatile, giving off vapors having a smell characteristic of other chlorinated solvents, somewhat similar to the tetrachloroethylene smell reminiscent of dry cleaners' shops. Note F and Cl are both in group 17 and can replace each other. They have the same general structure.
