The video series on hybridization did a great job helping me understand it conceptually rather than just being able to identify species hybridization based on appearance. The vids help so much more than my textbook lol
At 12:10 i guess you miscount the carbon atom that's attached to the oxygen atom by sigma and pie bond, which makes it 12 atoms that are sp2 hybridized....!
i passed organic chemistry by some miracle a year and a half ago now im going into university and are already acredited for organic 1 so im going straight into organic 2. Using your videos to go over the complete course and hopefully not struggle in the fall. So far the video explained concepts i left confused super well. Thank you so much.
I'm so happy to hear that! For even more help with organic 2 topics and more, I recommend joining the organic chemistry study hall. Details: leah4sci.com/join or contact me through my website leah4sci.com/contact/
On 5:22.... Carbon has sp3 hybridization , it can form bonds through one s and 3 p orbitals, How did you know that a bond of p orbital was missing, The s orbital could had lone electron , not???
Thank you for these wonderful videos! If you would be able to just clarify one thing? At 6:59, the carbon is single bound to a hydrogen, and it looks to me like the other lobe of the same sp orbital is then sigma binding to the adjacent carbon atom, would this not make 4 electrons in an orbital? One from each hydrogen (assuming both carbons have one hydrogen) and one from each carbon? Would there not be an sp orbital joining the hydrogen to the carbon and then another joining the carbon to carbon?
A single orbital can only hold 2 electrons. Each carbon in acetylene has 2 sp orbitals - one of those overlaps with the 1s atomic orbital of hydrogen and one of those overlaps with another sp orbital from the adjacent carbon. In both cases of 'overlap', only two electrons are present. For further questions, feel free to contact me through my website at leah4sci.com/contact/
Hi Leah, great video! I had a question about the question at the end where you counted 11 sp2 orbitals. Is that because each of the resonance oxygens counts as half?
Good question! I actually had an error in this video. You can see the note in the description that says: Note: At 12:12, the count of sp2 hybridized atoms is incorrect. There are 12 (not 11) sp2 hybridized atoms in this structure.

Nitrogen has 5 valence electrons. In this particular structure, three of those have been used in single bonds to adjacent carbons. That leaves two electrons remaining in a lone pair on the nitrogen itself. Make sure to watch my Lewis Structures for Organic Chemistry video here: th-cam.com/video/ozSyxZ0wlCM/w-d-xo.html
at 12:10, you count 11 sp2 hybrid orbitals, but there are 12. Can you overlay some text with the correction to the video? I've seen videos where errors are corrected in this way.

~2 days worth of lecture explained in under 14 min. What a godsend.
So glad to help!

I'm so glad to hear that! I love knowing that my resources helped you to understand. And I always prefer a video over a textbook :)

Oh wow you're right, I marked 12 and wrote 11
Good catch! Thank you
sp2 there is 12 not 11 right ??
haha i counted 3 times, cause i trust her a lot (i am usually the one who make mistakes not Leah ) agree 12 sp2
@@shaki6500 thank god, I thought I was losing my mind
@@sherylmassie9502 lol me tooo
Good catch, yes I miscounted! Glad you caught it and hopefully everyone reads this comment to catch the mistake as well

You're the most amazing tutor I have encountered since I was born.
Thanks so much! :)
This entire playlist is so helpful and effective
Glad you like it!
On 5:22....
Carbon has sp3 hybridization , it can form bonds through one s and 3 p orbitals,
How did you know that a bond of p orbital was missing, The s orbital could had lone electron , not???
No, don't forget to study the ground state configuration so you know where the electrons reside initially. See my series here: leah4sci.com/introorgo
YOU ARE THE BEST ! Thank you so much for spending your time doing this !!!!
You're so welcome, I'm happy to help!

U give awesome analogies
thanks!
Hi Leah, great video! I had a question about the question at the end where you counted 11 sp2 orbitals. Is that because each of the resonance oxygens counts as half?
Good question! I actually had an error in this video. You can see the note in the description that says:
Note: At 12:12, the count of sp2 hybridized atoms is incorrect. There are 12 (not 11) sp2 hybridized atoms in this structure.
This is a bit confusing :(
I'm sorry that it's still confusing for you, I know it can be.
sp2 there are 12 not 11, this still has not been corrected. Please consider fixing this or explaining why you only counted 11.
At which part of the video please?
@@Leah4sci around 12:06. I think you forgot the carbon in the carbonyl at the top.
There are limited electrons so why need the orbitals s p d f??
Are there valance electrons in pi orbital....
at which point in the video?
I really need your help in chemistry

sp orbital why draw arrows in in the P when there are empty orbitals just sp and 2 empty p?
at which point in the video?
why does nitrogen have a lone pair?
Nitrogen has 5 valence electrons. In this particular structure, three of those have been used in single bonds to adjacent carbons. That leaves two electrons remaining in a lone pair on the nitrogen itself.

@@Leah4sci Thank you!
you are an amazing teacher
Thank you!
thank you for the videos, they are very helpful
You're very welcome, happy to help!
12 sp2 for sure. She forgets to count the carbon linked to carbonyl on top, i think...
+Leah Fisch I also thought 12 sp2 bonds isn't it?
at 12:10, you count 11 sp2 hybrid orbitals, but there are 12. Can you overlay some text with the correction to the video? I've seen videos where errors are corrected in this way.
Thanks for catching this, yes there is a mistake here
You re the best
Thanks!
amazing voice
thank you
Thank You
You're welcome!
Thanks
you're welcome
its not clear but anyway thankful???¿???
Sorry it wasn't as clear as you hoped!
its a little bit confusion teacher other wise amazing lecture
Why is it confusing?
videos are good Leah but you could have explained this in more easier way to understand
Everyone has their way, for me, this is easier. :)
