benzene ring electrons

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..

The halogen atom is ortho and para directing and therefore, substitution takes place at ortho and para positions giving electrophilic substitution reactions at the benzene ring. In the resonance structures of chlorobenzene the ortho and para positions get negatively charged, i...

Amiline is a hybrid of the following resonating structures...

. Aromatic nitro compounds like nitro benzene has a smell of bitter almonds. iii) Nitro alkanes are sparingly soluble in water (lower members are relatively more soluble than the higher members). Aromatic nitro compounds are not soluble in water. They are soluble in organic solvents. iv) ..

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 benzen..

Toluene o-Nitrotoluene p-Nitrotoluene These groups (except halogens) increase the electron density at the ring through resonance effect. Thus the reactivity of benzene ring towards electrophilic substitution reactions increases. The substituents or groups whi..

Aliphatic amines have a pyramidal shape that is approximately tetrahedral when we assume the electron pair on nitrogen as a group. An amine which has 3 different groups attached to nitrogen has chiral nitrogen. But such amines cannot be resolved into enantiomers because of rapid inversion..

Aromatic compounds can be directly nitrated using a mixture of concentrated nitric acid and sulphuric acid. This reaction is an example of electrophilic substitution of benzene. The electrophile is a nitroni..

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 repr..
