The equations for the preparation of each of the given compounds from anisole and any necessary organic or inorganic reagents are to be written. Concept introduction: All activating substituents attached to an aromatic ring are ortho and para directing. Halogen substituents are ortho and para-directing but slightly deactivating. Strongly deactivating substituents are meta directing. If a benzene ring is attached to two or more substituents, the site of further substitution is decided by the combined effect of its substituents. The regioselectivity is determined by the more activating substituent. Friedel Craft alkylation takes place using an alkyl chloride in the presence of aluminum chloride. Sulfonation of benzene is carried out using sulfur trioxide in the presence of sulfuric acid. Halogenation of benzene is carried out using a suitable halogen in the presence of a Lewis acid.
