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. It can exist as either of two geometric isomers, cis-1,2-dichloroethene or trans-1,2-dichloroethene, but is often used as a mixture of the two ...
The chemical compound 1,2-dichloroethane, commonly known as ethylene dichloride (EDC), is a chlorinated hydrocarbon. It is a colourless liquid with a chloroform -like odour . The most common use of 1,2-dichloroethane is in the production of vinyl chloride , which is used to make polyvinyl chloride (PVC) pipes, furniture and automobile ...

The gauche effect is very sensitive to solvent effects, due to the large difference in polarity between the two conformers.For example, 2,3-dinitro-2,3-dimethylbutane, which in the solid state exists only in the gauche conformation, prefers the gauche conformer in benzene solution by a ratio of 79:21, but in carbon tetrachloride, it prefers the anti conformer by a ratio of 58:42.

trans-Dichlorobis(ethylenediamine)cobalt(III) chloride is a salt with the formula [CoCl 2 (en) 2]Cl (en = ethylenediamine). It is a green diamagnetic solid that is soluble in water. It is the monochloride salt of the cationic coordination complex [CoCl 2 (en) 2] +. One chloride ion in this salt readily undergoes ion exchange but the two other ...
1,1-Dichloro-2,2-difluoroethylene is a low-boiling liquid that is used a refrigerant. [3] It may also be used as a solvent, but has practical limitations as such, because of its low boiling point (commercial listings, 19 °C; lit. 17 °C).
