What is a localized and delocalized Bond?

[Alex Kashou]

I have no idea what the terms mean to be honest. Is localized meaning that it is just sigma bonds?

[DianaTrujillo2K]

Localized electrons stay in between two atoms. Delocalized electrons are not confined to any space and go outside their boundaries.

[Isaiah Little 1A 14B]

A delocalized bond usually involves resonance between different bond types. For example, the double and single bonds of each carbon in a benzene ring resonate between double in single bonds; therefore, the double bonds are delocalized because they are not defined to a certain region.

Delocalized bonds are not constricted to one nucleus as localized bonds are. Resonance structures are a good example of delocalized bonding because as we learned, resonance structures exhibit single/double or single/triple etc character throughout the molecule even though each lewis structure shows the bonds in different positions.

A localized bond pair travels between two atoms. A bond pair that moves between two different pairs of atoms is considered delocalized. You can identify delocalized bonds by checking the electron locations in two different resonance forms; if the pair changes location and form, it is delocalized.

To simplify it, localized bonds are bonds formed by two overlapping molecular orbitals
