Bromide is a halide anion and a monoatomic bromine. It is a conjugate base of a hydrogen bromide. In nature, bromine is most abundant as a bromide ion. Physiologically, it exists as an ion in the body. A bromide is a chemical compound containing a bromide ion or ligand. Bromide compounds, especially potassium …
Bromomethane (methyl bromide) is the most effective soil fumigant for killing plant pests, its use is being phased out because its emissions from soil can lead to stratospheric ozone depletion. The bimolecular nucleophilic substitution (S(N)2) reaction of methyl bromide and OH-in aqueous solution has been investigated using a multilayered-representation …

Methyl bromide is ubiquitous in the environment, because it is generated naturally by oceans, biomass burning, and plants. For industrial purposes, methyl bromide is produced by direct bromination of methane and by the hydrobromination of methanol (Davis et al. 1977; O'Neil et al. 2001; Ioffe and Kampf 2002).Sulfur or hydrogen sulfide …

Methyl bromide is a colorless gas at room temperature and a liquid below 38.5�F (3.6�C) or when compressed. It is usually shipped as a liquefied, compressed gas. It is odorless and nonirritating at low concentrations and has a musty or fruity odor at high concentrations (greater than 1,000 ppm). Because methyl bromide lacks adequate …
Bromine is a naturally occurring halogen element with atomic symbol Br, atomic number 35, and atomic mass 79.904. Bromine, which is found in the earth's crust and sea water, is used in many industrial processes, as well as in insecticides, fire extinguishers, pharmaceuticals, and food and drink products.
