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 (H) is :
