Compounds that contain a nitro group, e.g., picric acid and trinitrotoluene (TNT), are called nitro compounds; many nitro compounds are unstable and are used as explosives. As a result of the chemical bonding in the nitro group, the nitrogen atom is positively charged and each oxygen atom has a partial negative charge. For this reason the nitro group has a powerful attraction for electrons. Many of the chemical reactions of nitro compounds are due to this electronegativity electronegativity , in chemistry, tendency for an atom to attract a pair of electrons that it shares with another atom (see chemical bond). For example, the molecule hydrogen chloride, HCl, consists of a hydrogen atom, H, and a chlorine atom, Cl, sharing a pair of ..... Click the link for more information. of the nitro group.
