Most favourable conditions for inoic bonding are .

The -NO_(2) group in an aromatic ring deactivates the ortho and para positions for an electrophilic attack. When -NO_(2) group is present at ortho or para positions of a leaving group (Nucleofuge) it activates the ring for nucleophilic attack. The reduction of -NO_(2) group by metal in acid causes its reduction to -NH_(2) group and then the ring becomes strongly activated for a electrophilic attack. The strong activation of -NH_(2) group is moderated by its acylation with CH_(3)COCl to -NHAc group. Deacylation is carried out by hydrolysis with H_(3)O^(+) or OH^(-) . The ring alkylation by using RX//AlX_(3) is not possible in presence of -NO_(2) or -NH_(2) group but is possible in presence of -NHAc group. The product (G) is :

The general electrophilic substitution reaction (replacement of H. by an electrophilic which is an electron deficient species) in aromatic ring is represented as followed. An electrophilic attacks on ortho and para positions which respect to a stronger +m group are present in benzene ring and the electrophilie attacks at meta position with respect to stronger -m group if two -m groups are present in benzene ring. The product of the following reaction is
