benzene ring with nh2

After taking into account account the above observed facts, Kekule (1865) suggested a ring structure for benzene. According to him, six carbon atoms occupied six corners of a regular hexagon in benzene and each carbon carried one hydrogen atom. To satisfy the tetraval..

. Hence sideways overlapping of '2p' orbitals of carbon atoms can form two sets of p -bonds as show..

Halogenation of arenes is an electrophilic substitution reaction. The function of the halogen carrier is to generate 'electrophile' which attacks the benzene ring to form the product. With excess halogen, the second halogen also gets introduced in the ring at ortho and..

Aromatic compounds are those carbocyclic compounds that contain at least one benzene ring. The ring of six carbons in benzene or any of its derivatives is termed benzene ring or nucleus. A benzene ring may be represente..

Monocyclic arenes * contain only one benzene ring in their molecules. The general formula C n H 2 n - 6 , can describe monocyclic arenes such as benzene. Benzene is the simplest member of the arene family. The derivatives of benzene in..

. Electron releasing substituents like -CH 3 , -OCH 3 , -OH, -NH 2 etc activate the ring and stabilize the carbocation while electron withdrawing groups like -NO 2 , -CN, -SO 3 H, -X activate the carbocation. The nitrating mixture of conc H 2 SO 4 a..

Monosubstituted arenes Isomerism is not shown by monosubstituted benzene having methyl or ethyl group as the side chain, because all the positions on benzene ring are identica..

(c) is chlorobenzene, an aryl halide because the chlorine is directly attached to the benzene ring. (a), is benzyl chloride which is a substituted haloarene, while (b) is chlorocyclohexane which is a haloalkan..

The nitro group strongly deactivates the benzene ring towards electrophilic substitution. Nitro group is electron withdrawing group and thus causes electron deficiency at ortho and para positrons as is clear from the resonating structures of nitro benzene..
