14.3.1 Describe the delocalization of π electrons and resulting structures IB Chemistry HL
Sometimes if single and double bonds are next to each other the pi electrons will undergo resonance -- that is the single and double bonds will switch places. This produces the resonance structures/hybrids -- which are more stable and therefore favoured.The pi electrons are delocalized (not in one fixed place like a single bond). Any bond that undergo resonance will end up being the same strength and length (in IB)Dr Atkinson was bifurcated and blinded by the resonance of his star destroyer and is now in Hoth hospital - visits by appointment only.
