resonance of benzene

The currently accepted structure was developed by the application of the theory of resonance proposed in 1933. This theory states that benzene is a resonance hybrid of the following canonical forms. Resonance hyb..

The contributing structures do not have real existence. These are only imaginary structures, proposed to explain the properties of the molecule. None of these 'resonance structures' can be prepared in the laboratory. Only the resonance hybrid is the real molecule structure. ..

. To account for this, two other structures were proposed: The actual molecule is said to be a resonance hybrid of these three structure..

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..

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...

The structure of a nitro group can be represented as a resonance hybrid of two equivalent zwitter ionic polar structure..

The possible isomers of the aromatic compound having molecular formula C 7 H 7 Cl are benzyl chloride and ortho chlorotoluene and para chlorotoluene...

. This occurs when the sigma ( s ) electrons of the H-C bond that is attached to an unsaturated system, such as double bond or a benzene ring, enter into conjugation with the unsaturated system. The concept of hyperconjugation was developed by Baker and Nathan and is also known as Baker a..
