Molecular structure of ammonia and its three-dimensional shape. It has a net dipole moment of 1.484 D. Dot and cross structure of ammonia. The ammonia molecule has a trigonal pyramidal shape, as predicted by the valence shell electron pair repulsion theory (VSEPR theory) with an experimentally determined bond angle of 106.7°. [36]

[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.
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 ]
Chloromethane, also called methyl chloride, Refrigerant-40, R-40 or HCC 40, is an organic compound with the chemical formula CH 3 Cl.One of the haloalkanes, it is a colorless, sweet-smelling, flammable gas.
The organic compound 1,1,1-trichloroethane, also known as methyl chloroform and chlorothene, is a chloroalkane with the chemical formula CH 3 CCl 3. It is an isomer of 1,1,2-trichloroethane . A colourless and sweet-smelling liquid, it was once produced industrially in large quantities for use as a solvent . [ 5 ]
Process of establishing partition equilibrium in a separatory funnel for ammonia in water and chloroform. For example, ammonia (NH 3) is soluble in both water (aq) and the organic solvent trichloromethane (CHCl 3) - two immiscible solvents. If ammonia is first dissolved in water, and then an equal volume of trichloromethane is added, and the ...
