2:41 Clear and concise explanation of what resonance (electron delocalization) means. Resonance is NOT a process. It does NOT mean that the electron is flipping back and forth around the molecule. It means that the elextrons are spread out.

A very well prepared, beautiful lesson and delivery. Thank you for uploading this:)

@ConfidentChemistry 3 года назад

I'm glad you liked it!

This is my fourth video watching on RU-vid on resonance structure and it is the first that actually made sense to me. Thank you soooooooo much.

@ConfidentChemistry 2 года назад

Yay! I'm so glad I was able to give you a clear explanation. That's my whole goal with this channel! :)

@CK-xk9vq 2 года назад

I wish you had more videos! This is the first video on resonance I've seen that has really helped. You explained things so thoroughly, exactly what I have been needing!! Is there any way you would be able to make a video on organic acid/base reactions (using arrows to show electron flow)? Or anything with acid/base stuff in Ochem. I need someone like you to explain it!!

@ConfidentChemistry 2 года назад

I wish I had more videos too! Working on trying to make more, balancing with life and my kiddos 😊. Thanks for your kind words. I really believe that anyone can understand organic chemistry, you just need it explained the right way for you. That’s the beauty of RU-vid, there are so many great options. I’m happy I get to be the one who helps a few people get it.

Really helpful video for what has been a very problematic section for me. Thank you so much.

@ellahmariedabajo5737 2 года назад

Thank you for this. You have such a warm vibe that eases up the tension of this course.

thank you so much!! I finally understood resonance and you’ve helped me with my test tomorrow!! Don’t stop with your videos please!! Brazil needs more teachers like you!

@ConfidentChemistry 2 года назад

I'm so glad! Thanks for the encouragement - a whole bunch more videos to come out this summer :) Wow, Brazil! I would love to go there one day!

@masudanasir1617 Год назад

I watched 3 different videos on resonance structures on RU-vid and this is the best for me, thank you so much🙏🙏 keep it up💪💪

What are possible resonance structures for 2,6 dichloro 1,4 benzoquinone?

@siddharthchauhan749 2 года назад

And if we have cl in place of nh2 15:42 then it will have 5 reso structure?

@abbieorozco942 Год назад

Super helpful video! however at 5:18 confused why you drew in only two hyrdogens on the right, when its a methyl group with three hyrdogens?

@destinyleblanc5112 Год назад

It should have three Hs - good eye, I saw that too. There should also be two hydrogens on the middle (second carbon).

@ConfidentChemistry Год назад

Hi! In the allyl cation, the carbon on the right as I drew it first has a positive formal charge. It is sp2 hybridized, so it has 3 bonds (one to a carbon, the other two to H’s) and then an empty p orbital. The left hand carbon is also sp2, but has four bonds (sigma and pi to other C, and two to H’s) and no formal charge. The middle carbon would have one implicit hydrogen, I didn’t draw it in. That carbon is also sp2 hybridized, with 2 sigma bonds to carbon atoms, one pi bond to the left hand carbon, and one bond to H (not shown). It is precisely because the right hand carbon is not a methyl group that resonance can happen! If it had 3 hydrogens, we would not be able to move the double bond over as this would give that carbon 5 bonds. Hope that is helpful!

@vix2740 2 года назад

Is correct that resonance can only take place with sp2 hybridised atoms?

@g.davidtenenbaum8563 2 года назад

On the last example of the aromatic ring, is it possible to draw resonance structures with the pi bond closest to the N moving to form a double bond to the N creating a negative charge on the N? Followed by the rest of the pi bonds in the ring moving one bond over creating positive charges ( with the understanding that positive charges on C are less desirable than negative charges on N)? If so, would these be considered insignificant?

@ConfidentChemistry 2 года назад

Hi David! Sorry I missed your comment. If you're asking what I think you're asking, the answer would be no, since the nitrogen already has 3 bonds and one lone pair, it can't accept an extra bond - this would violate its octet!
