WHAT IS EFFECT OF SULPHURIC ACID ON CHLOROBENZENE
Answers
Answer:
Chlorine is an o/p-directing group.
Actually, the chlorine is electronegative species but it has lone pair of electrons which has tendency to be added in resonance structure of benzene ring and, so these lone pair electrons arises the partial -ve charge on ortho and para position so that the electron density is minimum at meta position.
Now, we know that when sulphuric acid is added to this compound the mechanism follows electrophile (SO3)attacks and since it it will approach to the position with more electron density and thus it attacks on -ve , ortho /para positions and so the result obtained is ortho and para chloro sulphonic acid.
Chlorobenzene tends to readily react with Chloral in the presence of some sulfuric acid to produce a compound called DDT. An acronym for DDT is Dichloro Diphenyl Trichloroethane. This DDT is popularly used as an insecticide. the name of this
p , p - dichloro diphenyl trichloro ethane
