Understanding resonance structures is the first step. Knowing which electrons CAN and CAN'T is key to figuring out how to draw additional resonance structures.
This video shows you what to avoid when drawing resonance, followed by key arrow patterns to look out for in determining additional structures.

thank you so much for this videos…i’m having my exam in 2days and all im doing is going through your video..thank you again…
do you have the solution of the assignment?
Hi Leah! I LOVE your site!!! In you example of 1,3- butadiene, the first Carbon loses it’s pi bond and therefore cannot fulfill the octet rule. Do can carbons in resonance structures violate this rule?
Great video! I have a question, though: In rule number 3, in that first resonance structure, didn’t the first carbon of the chain violate the octet? It seemed to have 6 electrons around it.
Thanks!
