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. It is produced on a large scale from benzene as a precursor to aniline.
Nitrobenzenes are a group of nitro compounds consisting of one or more nitro groups as substituents on a benzene core. They have the formula C 6 H 6–n (NO 2) n, where n = 1–6 is the number of nitro groups.
If the benzene ring contains other substituents, it belongs in Category:Nitrobenzene derivatives Wikimedia Commons has media related to Nitrobenzenes . The main article for this category is Nitrobenzenes .
2-Fluoronitrobenzene is an organic compound with the formula FC 6 H 4 NO 2. It is one of three isomeric fluoronitrobenzenes. [1] A colorless liquid, it is prepared from 2-nitrochlorobenzene using the Halex process: O 2 NC 6 H 4 Cl + KF → O 2 NC 6 H 4 F + KCl
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.
1,2,4,5-Tetrachloro-3-nitrobenzene (tecnazene) is an organic compound with the formula HC 6 Cl 4 NO 2. It is a colorless solid. A related isomer is 1,2,3,4-tetrachloro-5-nitrobenzene. It is used as a standard for quantitative analysis by nuclear magnetic resonance. [4] [5]

Disperse Yellow 42, a popular dye for polyesters, is derived from 1,4-dichloro-2-nitrobenzene. [1] 1,4-Dichloro-2-nitrobenzene is an organic compound with the formula C 6 H 3 Cl 2 NO 2. One of several isomers of dichloronitrobenzene, it is a yellow solid that is insoluble in water. It is produced by nitration of 1,4-dichlorobenzene. It is a ...
