What is resonance and resonating structures? |
| Answer» ResonanceIt is given by\xa0Heisenberg.He took a molecule of ozone. Its structure was represented as:According to the structure, it is clearly seen that it has one double bond and another single bond. So, obviously the bond lengths will be different. For double bond between oxygen atoms, the bond length is 121pm and for single bond it is 148pm.Resonance structures: Is defined as difference between actual bond energy and energy of most stable resonating structures.\xa0\tResonance averages the bond characteristics of a molecule as a whole.\tResonance stabilizes the molecule because energy of the resonance hybrid is less than the energy of any canonical forms. | |
