Webb7) Draw bonds to connect unpaired electrons in each pi system. These bonds represent the pi-bonds in the resonance contributor. Remember: stable structures form the maximum number of pi- bonds. Any pi system which has more than one unpaired electron after the bonds are drawn is unstable and can be removed. All remaining structures are valid. WebbIn which how many π bonds are in resonance?
