Bromine anion name

Hydrobromic acid. HBr is a binary acid it doesn t contain oxygen, so it isn t an oxy-acid. You begin by writing hydro-. Next, change the ending of the anion name, bromine, to -ic and write bromic after hydro- Write acid at the end, and you re done ... 

For example, the anion formed from brom/ne is named bromide (brom-l-ide). Therefore, the compound formed from the metal calcium and the nonmetal bromine is named calcium bromide. 

Another way to use pyridine in brominations is to make a stable crystalline compound to replace the dangerous liquid bromine. This compound, known by names such as pyridinium tribromide, is simply a salt of pyridine with the anion Brj. It can be used to brominate reactive compounds such as alkenes (Chapter 20). 

To name a binary compound containing metal and a non-metal, write the name of the metal first and the name of the non-metal second. For example, a compound that contains potassium as the cation and bromine as the anion is called potassium bromide. Be sure to indicate the valence if necessary, using the Stock system. For example, a compound that contains Pb2+ and oxygen is called lead(II) oxide. 

Iodine is produced by similar methods, namely, oxidation of the iodide anion from brines by chlorine. However, iodine is also produced in a reductive process by reacting NalOs, extracted from the natural source of Chilean saltpeter, with sodium hydrogen snffite. The pentavalent iodine is reduced to iodide (equations), which is then treated and oxidized with a sufficient amonnt of the mother liquor to liberate elemental iodine (equation 5). In contrast to chlorine and bromine, which have large industrial uses, iodine has no predominant commercial use. 

The formation of color centers in the alkali halides, especially silver, has been studied extensively and in great detail, in an attempt to understand the photographic process. At least half a dozen color centers have been identified in these materials, of which the most widely studied is probably the F center, defined as an electron trapped at an anion vacancy. The name comes from the German word for color Farbe. In the case of KBr, the F center (Fig. 16.7) is believed to be an electron trapped at a bromine vacancy. The F center can be modeled by assuming the electron is trapped in a box of side d, which scales with the lattice parameter of the alkali halide. The F center transition is believed to be between the ground and first excited state of this particle in a box. This model, while crude, qualitatively explains the data for some of the alkali halide F center spectra.

In contrast to the well-known alkylation paths, namely, S l and Sn2, the fluoroalkylation reaction was rationalized by an unusual ionic chain mechanism [26]. As shown in Scheme 14.3, the reaction was initiated with the direct attack of electron-positive bromine (5+) on the BrCF2CF2Br by phenoxide. Tetrafluoroethy-lene (CF2=CF2) was generated in situ after loss of bromide anions. The phenoxides added to the CF2=CF2 to give the reactive fluorocarbanions, which were quickly terminated by bromide to form 2-bromo-tetrafluoroethyl aryl ethers. In the elimination step, zinc inserted into the C—Br bond of 2-bromo-tetrafluorethyl aryl ethers in a similar way to the preparation of Grignard reagents. Finally, the aryl trifluorovinyl ethers were obtained by the elimination of ZnBrF salt at elevated temperature. 

The names of the monatomic anions are obtained from a stem name of the element followed by the suffix -ide. Example Br is called bromide ion, from the stem name brom- for bromine and the suffix -ide. 

The cation is calcium. The anion is from bromine, which becomes bromide. The correct name is calcium bromide.
