What are the isomers of dinitrobenzene?
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 C6H4N2O4 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.
What is the structure of meta-dinitrobenzene?
The crystal of meta-dinitrobenzene, C6H 4(N O2)2, is orthorhombic pyramidal. The dimensions of the unit cell, which contains 4 molecules, are a = 13.3A, b = 14.1 A, c = 3.80A and the space group is Pbn.
What is the type of m-dinitrobenzene?

How many isomers does dinitrobenzene have?
three isomers
isomers and of the mixture Dinitrobenzene (DNB) production yields a mixture of the three isomers.
Is m-dinitrobenzene a solid?
Dinitrobenzene is a pale yellow or white crystalline (sand- like) solid which is usually a mixture of three isomers. It is used in making dyes, other chemicals, and explosives. * Dinitrobenzene is on the Hazardous Substance List because it is regulated by OSHA and cited by ACGIH, DOT, NIOSH, DEP, IRIS, NFPA and EPA.
Which solvent is used for the recrystallization of m-dinitrobenzene?
The dinitrobenzene dissolve with methanol liquid obtaining is down to normal temperature, carries out suction filtration, and the crystal that suction filtration obtains adds in 250ml there-necked flask, then adds methyl alcohol 94.0g to dissolve.

How do you separate dinitrobenzene and nitrobenzene?
Nitrobenzene from reaction mixture can be removed by extracting the reaction mixture with ether.
Which two acids are used in synthesis of m-dinitrobenzene?
Synthesis of m-dinitrobenzene is a type of nitration reaction. It is a process where one or more of the H atoms from aromatic hydrocarbons are replaced with a nitro group –NO2. The reaction is generally carried out in presence of fuming nitric acid and conc. Sulphuric acid (mixed acid agent).

What are the isomers of dinitrobenzenes?
Dinitrobenzenes are chemical compounds composed of a benzene ring and two nitro group (-NO 2) substituents. The three possible arrangements of the nitro groups afford three isomers, 1,2-dinitrobenzene, 1,3-dinitrobenzene, and 1,4-dinitrobenzene.
What is the difference between 1 3 dinitrobenzene and M-dinitro benzene?
1,3-dinitrobenzene is a dinitrobenzene that is benzene disubstituted at positions 1 and 3 with nitro groups. It has a role as a neurotoxin. M-dinitrobenzene is a yellow solid with a slight odor. Sinks in water. (USCG, 1999) 1,3-dinitrobenzene
What is the concentration of dinitrobenzene in effluent water?
The concentration of 1,3-dinitrobenzene in an extract of effluent water from organics and plastics industries was 1,055 ng/ul (1). 1,3-Dinitrobenzene has been detected in the effluent of facilities that produce 2,4,6-trinitrotoluene ( TNT) at a concn of 4 ppm (2).
Is dinitrobenzene toxic to humans?
Hazards. Mixture of 1,3-dinitrobenzene with tetranitromethane was found highly explosive [Urbanski, 1964, vol. 1, 592]. 1,2-dinitrobenzene is a severe explosion hazard when shocked or exposed to heat or flame. When heated to decomposition all dinitrobenzens emit toxic fumes of nitrogen oxides [Sax, 9th ed., 1996, p. 1374].
