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.
In organic chemistry, an addition reaction is an organic reaction in which two or more molecules combine to form a larger molecule called the adduct. [1] [2]An addition reaction is limited to chemical compounds that have multiple bonds.

Ethylene (IUPAC name: ethene) is a hydrocarbon which has the formula C 2 H 4 or H 2 C=CH 2.It is a colourless, flammable gas with a faint "sweet and musky" odour when pure. [7] It is the simplest alkene (a hydrocarbon with carbon–carbon double bonds).
CaO + Br 2 + HCO 2 H → CaBr 2 + H 2 O + CO 2. Solid calcium bromide adopts the rutile structure, featuring octahedral Ca 2+ centres bound to six bromide anions, which also bridge to other Ca 2+ centres. When strongly heated in air, calcium bromide reacts with oxygen to produce calcium oxide and bromine: 2 CaBr 2 + O 2 → 2 CaO + 2 Br 2
The discovery and categorization of heterolytic bond fission was clearly dependent on the discovery and categorization of the chemical bond. In 1916, chemist Gilbert N. Lewis developed the concept of the electron-pair bond, in which two atoms share one to six electrons, thus forming the single electron bond, a single bond, a double bond, or a triple bond. [3]
Bromine dioxide (BrO 2). Bromine can form several different oxides: . Dibromine monoxide (Br 2 O); Bromine dioxide (BrO 2); Dibromine trioxide (Br 2 O 3); Dibromine pentoxide (Br 2 O 5); Tribromine octoxide (Br 3 O 8)
