Nature of the C-X bond in haloarenes; preparation by Sandmeyer and Gattermann reactions and by electrophilic substitution
Physical properties of haloarenes
Electrophilic substitution (chlorination, nitration, sulphonation) with mechanism; ortho-para directing influence of halogen
Nucleophilic substitution (replacement of Cl by -OH and -NH2) with mechanism; reduction to benzene
Wurtz-Fittig and Fittig reactions; Grignard reagent formation; structure and effects of DDT
