 that consists of a nitrogen atom joined to two oxygen atoms. 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 electronegativityelectronegativity
, 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 electrons.

Its known that the acid-strengthening effect of the nitro group is greater in the para position due to the negative charge of the phenoxide ion is delocalized onto an oxygen of the nitro group and therefore PNF is more acidic than MNF.
