The following groups are ortho-para directors. (a) (b) Br (c) OCH3 (d) (e) NH2 Draw a contributing structure for the resonance-stabilized cation formed during electrophilic aromatic substitution that shows the role of each group in stabilizing the intermediate by further delocalizing its positive charge.
