Which of the following statements regarding the concept of resonance is wrong?
The different resonating structures of a molecule have fixed arrangement of atomic nuclei.
The different resonating structures differ in the arrangement of electrons.
None of the individual resonating structures explains the various characteristics of the molecule.
The hybrid structures have equal contribution from all the resonating structures.
Statement (4) is wrong because resonating structures have different stabilities and therefore, their contributions to the hybrid structures are different.
