Resonance and energy

Postby Deborah Cheng 1F » Sat Nov 04, 2017 3:32 pm

Why does resonance lower the energy of a molecule?

Resonance structures spread multiple bond characters over a molecule, lowering the overall energy of the molecule.

Resonance structures are delocalized, which means the bond pair is distributed to multiples pairs of atoms and not just one pair of atoms. Because of this, the energy is lower which also makes the molecule more stable.
