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

AThe contributing structures must have the same number of unpaired electrons
BThe contributing structures should have almost similar energies
CThe contributing structures should be so written that unlike charges reside on atoms that are far apart
Correct Answer
DThe positive charge should be present on the electropositive element and the negative charge on the electronegative element

Solution

There is no restrictions that the resonating structures should have $$+ve$$ and $$-ve$$ charges on atom that are far apart. While other statements are correct.
