They have the formula C 6 H 6–n F n, where n = 1–6 is the number of fluorine atoms. Depending on the number of fluorine substituents, there may be several constitutional isomers possible. [1] Monofluorobenzene; Difluorobenzene. 1,2-Difluorobenzene; 1,3-Difluorobenzene; 1,4-Difluorobenzene; Trifluorobenzene. 1,2,3-Trifluorobenzene; 1,2,4 ...
1,2-Difluorobenzene, also known as DFB, is an aromatic compound with formula C 6 H 4 F 2. This colorless flammable liquid is a solvent used in the electrochemical studies of transition metal complexes .
1,3-Dichlorobenzene (also known as meta-dichlorobenzene) is an aryl chloride and isomer of dichlorobenzene with the formula C 6 H 4 Cl 2.It is the least common of the three isomers of dichlorobenzene, and it is a colorless liquid that is insoluble in water.

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.
trans-1,3,3,3-Tetrafluoropropene (HFO-1234ze(E), R-1234ze(E)) is a hydrofluoroolefin. It was developed as a "fourth generation" refrigerant to replace fluids such as R-134a , as a blowing agent for foam and aerosol applications, and in air horns and gas dusters . [ 3 ]
