Dichlorobenzene refers to three different compounds, all three consist of two chloro groups attached to a benzene ring. The differences arise from the different orientations around the ring the two chloro groups can attach to the benzene. The compounds are:
* 1,2-Dichlorobenzene or ortho-dichlorobenzene * 1,3-Dichlorobenzene or meta-dichlorobenzene * 1,4-Dichlorobenzene or para-dichlorobenzene
Ortho-dichlorobenzene
It is mainly used as a precursor to 1,2-dichloro-4-nitrobenzene, an intermediate in the synthesis of agrochemicals. In terms of niche applications, it is a versatile, nonflammable, high-boiling solvent. It is an insecticide for termites and locust borers. It is also used in softening and removing carbon-based contamination on metal surfaces.
Meta-dichlorobenzene
This finds no current uses, other than being isomeric contaminants in either chemicals.
Para-dichlorobenzene
It is used to control moths, moulds, and mildew. It finds use as a disinfectant in waste containers and restrooms and is the characteristic smell associated with urinal cakes. It also act as a precursor to other chemicals. The chlorides on para-dichlorobenzene can be substituted with oxygen, amine, and sulfide groups. In a growing application, it is the precursor to the high performance polymer poly(p-phenylene sulfide).
Two: 1,1-dichloroethane and 1,2-dichloroethane.
Regardless of the isomer dichlorobenzene will have 12 atoms in total: 6 carbon, 4 hydrogen, and 2 chlorine.
Para-dichlorobenzene crystal has covalent bonds between the carbon and chlorine atoms within the molecules. Additionally, it also has weak intermolecular forces such as van der Waals forces between the molecules holding the crystal lattice together.
p-Dichlorobenzene is a nonpolar molecule. It is composed of covalent bonds between carbon and chlorine atoms, which have similar electronegativities, leading to a symmetric distribution of charge and no separation of positive and negative charges across the molecule. It does not contain ions, so it is not ionic.
p-dichlorobenzene is nonpolar because the electronegativity of chlorine is similar to that of carbon, resulting in a symmetrical molecule. In cis-1,4-dichlorocyclohexane, the molecule is asymmetrical due to the arrangement of the chlorine atoms on the cyclohexane ring, leading to a net dipole moment and making it a polar molecule.
It is definitely a COVALENT Compound. NB Being dichlorobenzene, there are three options for the name , depending on the positions of the chlorine atoms on the benzene(carbon) ring. They are, ;- 1,2-dichlorobenzene 1,3- dichlorobenzene 1,4-dichlorobenzene. NNB There is no such molecule as 1,1-dichlorobenzene. In all three cases the chlorine in bonded covalently.
Dichlorobenzene
Two: 1,1-dichloroethane and 1,2-dichloroethane.
C6H4Cl2
One way to separate dichlorobenzene from silicon dioxide is to use a solvent extraction method, where dichlorobenzene can dissolve in a solvent like ethanol, while silicon dioxide remains insoluble. After mixing the mixture with ethanol, the solution can be filtered to separate the solid silicon dioxide from the solvent containing dichlorobenzene. The solvent can then be evaporated to isolate the pure dichlorobenzene.
The bonds are covalent.
Frequently used is 1,4-dichlorobenzene.
