(point group C2v) and the directions of dipole moment change for each vibration class. If we take chlorobenzene, an organic acid chloride, and an aluminum chloride (AlCl3) catalyst, an acylation reaction takes place and we install a ketone on our aromatic ring. It also can be used as a reaction solvent for a wide variety of organic reactions. Hence ortho and para substitution products are obtained on halogenation, nitration, sulfuration, etc. Sulfuration: A mixture of ortho and para Chlorobenzene sulfonic acid is obtained by the reaction of Chlorobenzene with the corresponding H2SO4. Since chlorobenzene has a relatively high boiling point, it can be used as a reaction solvent if a certain reaction requires a higher boiling point than would normally be allowed with another chlorinated solvent. In this flask, NaNO2 solution is added, resulting in benzenediazonium chloride. C6H5NH2 + NH2 + HCl → C6H5 – N = N – Cl + 2H2O.

It is used in the manufacture of aniline, phenole, chloronitrobenzene, and disinfectant DDT. Log in or sign up to add this lesson to a Custom Course. In alkyl halide, the bond between the halogen atom and the alkyl group is relatively weak. Alternatively, one can again number the hydrogen atoms and see that there are two unique orientations, related by rotations of n × 180 ° ( n = 0-1) around the C-Cl bond axis. In this reaction, we first make what's called a diazonium salt from aniline by the action of sodium nitrite NaNO2. In a flask, dissolve 20 gram aniline in dilute HCl and cool it to 5°C.
