Bromobenzene is prepared by the action of bromine on benzene in the presence of Lewis acid catalysts such as aluminium chloride or ferric bromide. [3]Bromobenzene is used to introduce a phenyl group into other compounds.
1,2-Dibromobenzene: 1,3-Dibromobenzene [1] 1,4-Dibromobenzene [2] [3] [4] Structure Molecular formula: C 6 H 4 Br 2: Molar mass: 235.906 g/mol Appearance colorless liquid colorless liquid white solid CAS number [583-53-9] [108-36-1] [106-37-6] Properties Density and phase: 1.9940 g/ml, liquid 1.9523 g/ml, liquid 1.84 g/ml, solid Solubility in ...
Nitrobenzene is an aromatic nitro compound and the simplest of the nitrobenzenes, with the chemical formula C 6 H 5 NO 2. It is a water-insoluble pale yellow oil with an almond -like odor. It freezes to give greenish-yellow crystals.
4-Fluorobromobenzene is synthesized via bromination of fluorobenzene in the presence of a Lewis acid catalyst such as iron(III) bromide or aluminium tribromide. [2]4-Bromofluorobenzene is regarded by the Toxic Substances Control Act as a high production volume chemical, that is, a chemical that 1 million pounds (about 500 tonnes) per year is either produced in or imported to the United States.
All three have been synthesized by various routes: 1-Bromo-2-chlorobenzene: from 2-chloroaniline, via diazotization followed by a Sandmeyer reaction [1]; 1-Bromo-3-chlorobenzene: by (3-chlorophenyl)trimethylgermanium by electrophilic substitution [2] [better source needed]
The three possible arrangements of the nitro groups afford three isomers, 1,2-dinitrobenzene, 1,3-dinitrobenzene, and 1,4-dinitrobenzene. Each isomer has the chemical formula C 6 H 4 N 2 O 4 and a molar mass of about 168.11 g/mol. 1,3-Dinitrobenzene is the most common isomer and it is used in the manufacture of explosives .

3-Nitrobenzaldehyde is an organic compound with the formula O 2 NC 6 H 4 CHO. It is one of three isomers of nitrobenzaldehyde. It contains a nitro group meta-substituted to the aldehyde. 3-Nitrobenzaldehyde is the primary product obtained via the mono-nitration of benzaldehyde with nitric acid. [3] C 6 H 5 CHO + HNO 3 → O 2 NC 6 H 4 CHO + H 2 O
