Not sure if you've mastered resonance structures? Looking for extra practice?
Resonance is a critical topic in your organic chemistry curriculum. After watching the Resonance Structures Video Series test your knowledge with this short quiz below.
Give it a shot, then check the solutions (linked at the end) and see how you did.
Resonance Structures Practice Question 1
Warm-up question: Draw all major resonance structures for the following polyatomic ions
For the step-by-step solution and explanations for Question 1, see my Resonance Practice Problems Video.
Resonance Structures Practice Question 2
Draw all resonance structures and indicate the major and minor contributors. Pay attention to octets!
Resonance Structures Practice Question 3

Such a wonderful site . Thank you , it’s of great help
you make love to my hated sugject
leaha why are you not active on your web did you stoped this
what are you diong now
Thanks and by the way us there any shirt tricks to find the no of resonat8ng structure for a compound
In question 4 do we assume that the Nitrogen in the ring has a hydrogen bonded to it? When I was working it out I was confused that there wasn’t a charge on the N because as it is written it looks like it is only bonded to the two carbons next to it in the ring but in the solution it has a hydrogen bonded to it as well
Hi, thanks for everything you are amazing and I learned a lot from you. But everytime I click on to get solution it said sent and I never get them, what should I do please.
Hi! Thanks so much for these great practice problems. Unfortunately after clicking on the solutions link I didn’t receive the solutions via email
Mam where is the answer key
how to email you cause link is not opening
i love the way u teaching! superb!
Thank you, Moin!

Hi Leah.
I followed your link but I couldn’t receive the solutions.
Please help me.
On question 3 and 4 you have extra Hydrogens on the Nitrogens for the solution sheet but not on the question. Why?
How come in number 8 the structures with Cl with a positive charge are major contributors? Shouldn’t it be a minor contributor because Cl is electronegative? Also, why are 1 and 4 minor contributors compared to 3? All have C with a positive charge.
Lindsay: Cl is highly electronegative and will resent a positive charge.
I am bothered by the same question as well. According to your video in resonance part 3, more electronegative atoms will resent to a negative charge.
No the negative charge will resonate to the more electronegative atoms. Electrons will never go to a negative means it already has too many electrons.
thanks for help
You’re welcome wael
Is the carbo-cation the right carbon in question 7? Or is it supposed to be the one that’s directly attached to the Oxygen?
Mistake on the quiz
where are the solutions to these problems?
There’s a link on the bottom of the page. Email me if you don’t see it
I still haven’t receive the solutions Leah. can u pls help me with it
