Following criteria should be taken in consideration for resonance. The major contributor is the one with the lower energy good contributors generally have all octets satisfied, as many bonds are possible andas little charge separation as possible negative charges are more stable on the more electronegative atoms. Resonance stabilization is most important when it serves to delocalize a charge over two or more atoms How many resonating structures can be drawn for 2, 4-pentadienyl radical
