Resonance - The phenomenon of resonance was put forward by Heisenberg to explain the properties of certain covalent molecules. Most covalent molecules have a unique Lewis formula (dot structure), which explains the bonding in that molecule. Some molecules lend themselv..

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 t..

If two or more structures can be assigned to a molecule, none of which is capable of describing all the known properties of the compound, then the actual structure is known to be a resonance hybrid or an intermediate of these structures. The various ..

The various contributing structures should have the same arrangements of structures but may differ only in electronic arrangement..

Resonance or Mesomeric Effect - If two or more structures can be assigned to a molecule, none of which is capable of describing all the known properties of the compound, then the actual structure is known to be a resonance hybrid or an intermediate of these h..

Due to resonance, the p -electron charge in benzene gets distributed over greater area, i.e., gets delocalized. Delocalization results in the energy of the resonance hybrid decreasing relative to the contributing structures, by about 150 kJ mol - 1 . This decrease i..

This structure explains the folding of a polypeptide chain. Two different types of secondary structures are observed. a -Helix The a -helix model postulated by Linus Pauling in 1951 was based purely on theoretical consideration but-- later verified experimentally. Figure drawn b..
