Which of the following conditions is not correct for resonating structures?

Option: 1

The contributing structures must have the same number of unpaired electrons.


Option: 2

The contributing structures should be so written that unlike charges reside on atoms that are far apart.


Option: 3

The contributing structures should have similar energies.


Option: 4

The positive charge should be present on the electropositive element and the negative charge on electronegative element.


Answers (1)

Resonance structures with similar charges on adjacent atoms are insignificant due to electrostatic repulsion and thus are unstable.

Therefore, there is no rule which states that positive charge and negative charge on atoms should be far apart.
Hence , correct option is (2)
