Current Question (ID: 7998)

Question:

An incorrect statement regarding resonating structures is :

Options:

1. The contributing structure must have the same number of unpaired electrons.
2. The contributing structures should have similar energies.
3. The resonance hybrid should have a higher energy than any of the contributing structures. (Correct)
4. None of the above.

Solution:

HINT: The resonance hybrid should have lower energy than any of the contributing structure. Explanation: Conditions of resonance are: 1. The relative position of all the atoms must be same in each resonating structures. 2. Number of paired and unpaired electrons in each resonating structure must be same so that there is a continuous change from one bond type to another bond type may occur. 3. Contributing structures should have almost equal energy . 4. Like charges should be greatly separated and unlikely charges should be placed together. 5. The more electropositive element should preferably have a positive charge and more electronegative element should have a negative . 6. The resonance hybrid should have lower energy than any of the contributing structure.
