Chloroform, [10] or trichloromethane (often abbreviated as TCM), is an organochloride with the formula C H Cl 3 and a common solvent. It is a volatile , colorless, sweet-smelling, dense liquid produced on a large scale as a precursor to refrigerants and PTFE . [ 11 ]
CuCl 2 reacts with HCl or other chloride sources to form complex ions: the red [CuCl 3] − (found in potassium trichloridocuprate(II) K[CuCl 3]) (it is a dimer in reality, [Cu 2 Cl 6] 2−, a couple of tetrahedrons that share an edge), and the green or yellow [CuCl 4] 2− (found in potassium tetrachloridocuprate(II) K 2 [CuCl 4]).
[1] [2] [3] Introduced by Gilbert N. Lewis in his 1916 article The Atom and the Molecule, a Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds. [4] Lewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond.

The naming of is group is derived from the methyl group (which has the formula –CH 3), by replacing each hydrogen atom by a chlorine atom. Compounds with this group are a subclass of the organochlorines. Some notable examples of compounds with this group are trichloromethane H– CCl 3, 1,1,1-trichloroethane H 3 C – CCl 3, and chloral HOC ...
