ANTHE helps students to know their potential at All India Level and prepare under the expert guidance of Aakash. The nitro group, \(\ce{-NO_2}\), like the carboxylate anion, is a hybrid of two equivalent resonance structures: The hybrid structure has a full positive charge on nitrogen and a half-negative charge on each oxygen. Aromatic nitro compounds undergo bimolecular reduction in alkaline medium.

The most common examples are organic substances in which a carbon atom is linked by a covalent bond to the nitrogen atom of the nitro group. You can give test from your Home.

In p – chloronitrobenzene, the two vector dipole moment act opposite to each other which partially cancel each other. This reaction is used to prepare 1 deg nitro compounds primarily while 2 deg and 3 deg halides give major proportion of alkenes due to β – elimination. Out of three sp2 hybrid orbitals of nitrogen one overlaps with alkyl group and two with oxygens while the unhybridized p orbital of N – atom containing a pair of electrons and lying perpendicular to the plane of hybrid orbitals overlaps sideway with half filled 2 p – orbitals of two oxygen atoms. Nitro derivatives of aromatic compounds like nitrobenzene are produced when benzene is allowed to react with nitrating mixture. Reading Time: 1min read 0. Explain. AI based online exam.

Alkyl and aromatic C-nitro compounds bearing electron-withdrawing groups such as NO 2 , Br, Cl and F were active nitrosating agents.

The resonance hybrid is shown as under which confirms the spectroscopic evidence that both nitrogen – oxygen bonds have same bond length. Share on Facebook Share on Twitter. This forms π- bond above and below the plane of molecule. Nitro compound, any of a family of chemical compounds in which the nitro group (―O―N=O) forms part of the molecular structure.
