Electronegativity TrendsAbility to Attract the Electrons in a Covalent Bond
Both Resonance Structures Contribute to the Actual Structure
Resonance Rules • Cannot break single (sigma) bonds • Only electrons move, not atoms 3 possibilities: • Lone pair of e- to adjacent bond position • Forms p bond - p bond to adjacent atom - p bond to adjacent bond position
Resonance Stabilization of IonsPositve charge is “delocalized”
