Bromotoluenes are aryl bromides based on toluene in which at least one aromatic hydrogen atom is replaced with a bromine atom. They have the general formula C 7 H 8–n Br n, where n = 1–5 is the number of bromine atoms.
Toluene (/ ˈ t ɒ l. j u iː n /), also known as toluol (/ ˈ t ɒ l. j u. ɒ l,-ɔː l,-oʊ l /), is a substituted aromatic hydrocarbon [15] with the chemical formula C 6 H 5 CH 3, often abbreviated as PhCH 3, where Ph stands for the phenyl group. It is a colorless, water-insoluble liquid with the odor associated with paint thinners.
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...

Together with other isomers, 4-nitrotoluene is prepared by nitration of toluene, [4] commonly using titanium(IV) nitrate. [5] It undergoes the reactions typical for nitrobenzene derivatives, e.g. hydrogenation gives p-toluidine. Oxidation of the methyl substituent of 4-nitrotoluene has been extensively investigated.
The simplest compound of bromine is hydrogen bromide, HBr. It is mainly used in the production of inorganic bromides and alkyl bromides, and as a catalyst for many reactions in organic chemistry. Industrially, it is mainly produced by the reaction of hydrogen gas with bromine gas at 200–400 °C with a platinum catalyst.
Bromine is a chemical element; it has symbol Br and atomic number 35. It is a volatile red-brown liquid at room temperature that evaporates readily to form a similarly coloured vapour. Its properties are intermediate between those of chlorine and iodine .
