Sodium bromide is an inorganic compound with the formula Na Br. It is a high-melting white, crystalline solid that resembles sodium chloride . It is a widely used source of the bromide ion and has many applications.
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.
Structure of N-bromosuccinimide, a common brominating reagent in organic chemistry. Like the other carbon–halogen bonds, the C–Br bond is a common functional group that forms part of core organic chemistry. Formally, compounds with this functional group may be considered organic derivatives of the bromide anion.
The classic case is sodium bromide, which fully dissociates in water: NaBr → Na + + Br −. Hydrogen bromide, which is a diatomic molecule, takes on salt-like properties upon contact with water to give an ionic solution called hydrobromic acid. The process is often described simplistically as involving formation of the hydronium salt of bromide:
Iron(III) bromide is the chemical compound with the formula FeBr 3. Also known as ferric bromide , this red-brown odorless compound is used as a Lewis acid catalyst in the halogenation of aromatic compounds .
It reacts with hydrogen or sodium to form HCo(CO) 4 or NaCo(CO) 4. It is a catalyst in carbonylation and hydrosilylation reactions. [23] Cobaltocene (Co(C 5 H 5) 2) is a cyclopentadiene complex of cobalt. It has 19 valence electrons and is easily oxidized to Co(C 5 H 5) + 2 with a stable structure of 18 electrons by reaction.

The sodium chloride (NaCl) polymorph is most common. A cubic close-packed arrangement of chloride anions with rubidium cations filling the octahedral holes describes this polymorph. [4] Both ions are six-coordinate in this arrangement. The lattice energy of this polymorph is only 3.2 kJ/mol less than the following structure's. [5]
In chemistry, the perbromate ion is the anion having the chemical formula BrO − 4. It is an oxyanion of bromine, the conjugate base of perbromic acid, in which bromine has the oxidation state +7. [1] Unlike its chlorine (ClO − 4) and iodine (IO − 4) analogs, it is difficult to synthesize. [2] It has tetrahedral molecular geometry. [3]
