2 → C 6 H 4 Cl 2 + HCl. The reaction also affords the 1,4- and small amounts of the 1,3-isomer. The 1,4- isomer is preferred over the 1,2- isomer due to steric hindrance. The 1,3- isomer is uncommon because it is a meta- compound, while chlorine, like all halogens, is an ortho/para-director in terms of electrophilic aromatic substitution.
1,2-Dichlorobenzene or ortho-dichlorobenzene; 1,3-Dichlorobenzene or meta-dichlorobenzene; 1,4-Dichlorobenzene or para-dichlorobenzene. All three isomers are colorless chlorobenzenes with the formula C 6 H 4 Cl 2. They differ structurally based on where the two chlorine atoms are attached to the ring.
They have the formula C 6 H 6–n Cl n, where n = 1–6 is the number of chlorine atoms. Depending on the number of chlorine substituents, there may be several constitutional isomers possible. Monochlorobenzene; Dichlorobenzene. 1,2-Dichlorobenzene; 1,3-Dichlorobenzene; 1,4-Dichlorobenzene; Trichlorobenzene. 1,2,3-Trichlorobenzene; 1,2,4 ...
C 60 in solution C 60 in extra virgin olive oil showing the characteristic purple color of pristine C 60 solutions. The solubility of fullerenes is generally low. Carbon disulfide dissolves 8g/L of C60, and the best solvent (1-chloronaphthalene) dissolves 53 g/L. up Still, fullerenes are the only known allotrope of carbon that can be dissolved in common solvents at room temperature.

1,2-Dichloro-4-nitrobenzene is an organic compound with the formula 1,2-Cl 2 C 6 H 3-4-NO 2. This pale yellow solid is related to 1,2-dichlorobenzene by the replacement of one H atom with a nitro functional group. This compound is an intermediate in the synthesis of agrochemicals.
Table data obtained from CRC Handbook of Chemistry and Physics 44th ed. The (s) annotation indicates temperature is equilibrium of vapor over solid. Otherwise temperature is equilibrium of vapor over liquid. log 10 of 1,2-dichloroethane vapor pressure.
