Question 11

Explain the important aspects of resonance with reference to the  ion.

Answer

In some molecules single Lewis structure fails to explain all the characteristics of the molecule. As a result a number of structures can be drawn to explain all the characteristic .Such structures are called resonating structures & resonance is defined as the phenomenon as a result of which a molecule can be expressed in different forms none of which can explain all the properties of the molecule. As in case of  ion all the C---- O bonds are equivalent. Therefore it is not correct to represent  ion through one Lewis strucuture. Instead three resonating structures can be drawn ,which are as follows:
