1,2-Dinitrobenzene is one of three isomers of dinitrobenzene, with the formula C 6 H 4 (NO 2) 2. The compound is a white or colorless solid that is soluble in organic solvents. It is prepared from 2-nitroaniline by diazotization and treatment with sodium nitrite in the presence of a copper catalyst. [1]
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.
Description: Ball-and-stick model of a 1,2-dinitrobenzene molecule, C 6 H 4 N 2 O 4, also known as ortho-dinitrobenzene or o-dinitrobenzene.The molecule is shown as found in the crystal structure reported in Acta Crystallogr.
They have the formula C 6 H 6–n (NO 2) n, where n = 1–6 is the number of nitro groups. Depending on the number of nitro groups, there may be several constitutional isomers possible. Mononitrobenzene; Dinitrobenzene. 1,2-Dinitrobenzene; 1,3-Dinitrobenzene; 1,4-Dinitrobenzene; Trinitrobenzene. 1,2,3-Trinitrobenzene; 1,2,4-Trinitrobenzene; 1,3 ...
