In case of haloalkanes, the halogen atom is attached to the sp3 hybridised carbon atom of an alkyl group whereas, in haloarenes, the halogen atom is attached to sp2 hybridised carbon atom of an aryl group. Haloalkanes are the halogen derivatives of hydrocarbons, and these are of the following types depending upon the number of hydrogen atoms present in them. Haloarenes are aromatic compounds in which the halogen atom is attached directly to the carbon atom of the aromatic ring. Haloalkanes and Haloarenes deal with the study of essential methods of preparation, physical and chemical properties and uses of organohalogen compounds. Describe the reactions involved in the preparation of haloalkanes and haloarenes and understand various reactions that they undergo. Correlate the structures of haloalkanes and haloarenes with multiple types of reactions; use stereochemistry as a tool for understanding the reaction mechanism. Appreciate the applications of organometallic compounds and highlight the environmental effects of polyhalogen compounds.
