The molecular formula C 2 H 4 Br 2 (molar mass: 187.86 g/mol, exact mass: 185.8680 u) may refer to: 1,1-Dibromoethane (ethylidene dibromide)
Calcium bromide is the name for compounds with the chemical formula Ca Br 2 (H 2 O) x. Individual compounds include the anhydrous material (x = 0), the hexahydrate (x = 6), and the rare dihydrate (x = 2). All are white powders that dissolve in water, and from these solutions crystallizes the hexahydrate.
A molecule that has carbon—heteroatom double bonds, such as a carbonyl group (C=O) or imine group (C=N), can undergo an addition reaction because its double-bond. An addition reaction is the reverse of an elimination reaction, in which one molecule divides into two or more molecules.
The compound has idealized C 2h symmetry. Each metal centre is pseudo-octahedral. The compound is prepared by the reaction of rhodium trichloride trihydrate and pentamethylcyclopentadiene in hot methanol, from which the product precipitates: [1] 2 C 5 (CH 3) 5 H + 2 RhCl 3 (H 2 O) 3 → [(C 5 (CH 3) 5)RhCl 2] 2 + 2 HCl + 6 H 2 O
The Appel reaction is an organic reaction that converts an alcohol into an alkyl chloride using triphenylphosphine and carbon tetrachloride. [1] The use of carbon tetrabromide or bromine as a halide source will yield alkyl bromides, whereas using carbon tetraiodide, methyl iodide or iodine gives alkyl iodides.
1,2-Dibromoethane, also known as ethylene dibromide (EDB), is an organobromine compound with the chemical formula C 2 H 4 Br 2. Although trace amounts occur naturally in the ocean, where it is probably formed by algae and kelp, substantial amounts are produced industrially. It is a dense colorless liquid with a faint, sweet odor, detectable at ...
Calcium peroxide or calcium dioxide is the inorganic compound with the formula CaO 2. It is the peroxide (O 2 2−) salt of Ca 2+. Commercial samples can be yellowish, but the pure compound is white. It is almost insoluble in water. [3]
Calcium bromate, Ca(BrO 3) 2, is a calcium salt of bromic acid. It is most commonly encountered as the monohydrate, Ca(BrO 3) 2 •H 2 O. [citation needed] It can be prepared by reacting calcium hydroxide with sodium bromate or calcium sulfate with barium bromate. Above 180 °C, calcium bromate decomposes to form calcium bromide and oxygen.
