Dichloromethane (DCM, methylene chloride, or methylene bichloride) is an organochlorine compound with the formula C H 2 Cl 2. This colorless, volatile liquid with a chloroform-like, sweet odor is widely used as a solvent. Although it is not miscible with water, it is slightly polar, and miscible with many organic solvents.

1,2-Dichloroethylene or 1,2-DCE is the name for a pair of organochlorine compounds with the molecular formula C 2 H 2 Cl 2.The two compounds are isomers, each being colorless liquids with a sweet odor.
Deuterated dichloromethane (CD 2 Cl 2 or C 2 H 2 Cl 2) [a] is a form (isotopologue) of dichloromethane (DCM, CH 2 Cl 2) in which the hydrogen atoms (H) are deuterium (heavy hydrogen) (2 H or D). [2] Deuterated DCM is not a common solvent used in NMR spectroscopy as it is expensive compared to deuterated chloroform .
Dibromomethane is prepared commercially from dichloromethane via bromochloromethane: 6 CH 2 Cl 2 + 3 Br 2 + 2 Al → 6 CH 2 BrCl + 2 AlCl 3 CH 2 Cl 2 + HBr → CH 2 BrCl + HCl. The latter route requires aluminium trichloride as a catalyst. [3] The bromochloromethane product from either reaction can further react in a similar manner:
Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.
