Using an acid ratio of 30/56/14, the product mix is typically 34-36% 2-nitrochlorobenzene and 63-65% 4-nitrochlorobenzene, with only about 1% 3-nitrochlorobenzene. Since the above synthetic route does not efficiently produce the 3-isomer, the route most commonly used by chemists is the chlorination of nitrobenzene.

3-Nitrotoluene or meta-nitrotoluene is an organic compound with the formula CH 3 C 6 H 4 NO 2. It is one of three isomers of nitrotoluene . A yellow liquid, it is used in the manufacture of meta -toluidine , which is an intermediate in the production of various dyes.
c 6 h 5 cl + hno 3 → o 2 nc 6 h 4 cl + h 2 o This reaction affords a mixture of isomers. Using an acid ratio of 30% nitric acid, 56% sulfuric acid and 14% water, the product mix is typically 34-36% 2-nitrochlorobenzene and 63-65% 4-nitrochlorobenzene , with only about 1% 3-nitrochlorobenzene .
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 ...

If there are multiple functional groups of the same type, either prefixed or suffixed, the position numbers are ordered numerically (thus ethane-1,2-diol, not ethane-2,1-diol.) The N position indicator for amines and amides comes before "1", e.g., CH 3 CH(CH 3)CH 2 NH(CH 3) is N,2-dimethylpropanamine.
2-Nitrotoluene or ortho-nitrotoluene is an organic compound with the formula CH 3 C 6 H 4 NO 2. It is pale yellow liquid that crystallizes in two forms, called α (−9.27 °C) and β (−3.17 °C). It is mainly a precursor to o-toluidine, which is an intermediate in the production of various dyes. [4]
