Delocalized Structures

Postby LMendoza 2I » Fri Oct 27, 2017 9:34 pm

Why is it that delocalized lewis structures are more stable? Also, why does it matter if a structure is more or less stable?

Delocalized electrons are electrons in a molecule, ion or solid metal that are not associated with a single atom or a covalent bond.
Delocalized electrons form partial double bonds, meaning the distance between electrons and atoms is further than the one in double bonds. In other words, the delocalized electrons have a higher possibility to locate close to the midpoint of two atoms than the electrons in double bonds do. Therefore, it takes more energy to move the delocalized electrons towards an atom in order to break a bond.
The partial double bonds are harder to be broken, making them more stable than double bonds.
Electrons in structures that are more stable are less active, so these electrons are less likely to react with other chemicals.

Delocalized Lewis dot structures are more stable simply because the resonant partial double bonds are the lowest possible energy of the structure.
