Resonance Structure

More than one valid Lewis Structure can be drawn for a molecule

• Resonance

• Octet rule

• Electronegativity

• Polar covalent

________________ are two Lewis structures with the same placement of atoms, but a different arrangement of electrons

_______________ is a composite of all possible resonance structures, representing the electron pairs with different locations of individual resonance structures as delocalized

Which resonance structure is best, according to formal charges?

• Structure 1

• Structure 2

• Structure 3

• All are equally valid as they are resonance forms.
