Taking organic chem over six weeks, in the Summer, is pretty rough... thank you so much for your videos, they've always been a great help but are really coming in clutch right now
You might not see this but if you do i really want to thank you because of you i passed my math GED test im still young and want to have a brighter future and math was my biggest struggle because of you i not only passed math but got a collage ready score Thank you so much
@@safwanshahriar9579 I meant “came on time”. It is crazy to see how bad my grammar was at the time this video was uploaded but I am happy I made some progress 😊.
9:53 - My professor said the most electronegative atom should have the negative charge as it is more stable, and if I am not wrong Oxygen is more electronegative than Sulfur so why is the negative charge placed on the Sulfur atom.
When going down ie top to bottom of periodic table we depend on size factor. So here, Sulphur is bigger in size than oxygen and so a negative charge on it would be more stable. (If you go period wise in periodic table ie horizontally then electronegativity is a factor which helps in comparing. )
The electron donating R groups (in this case methyls but think of all alkyl groups as electron donating) stabilize the positive charge on the carbon. The greater the substitution, the more stable the carbocation.
It is because of another effect called hyperconjugation(refer any other videos if you want to know more,its basically a no bond resonance) and hyper conjugation depends on the number of alpha hydrogens,i.e,hydrogen attached to sp³ hybridised carbon near to the charge.More the number of alpha hydrgen more stable the carbocation
@9:37 oxygen is more electron neg than sulfur, so wouldn't the major contributor be the structure where the neg charge is on the oxygen, not sulfur...?
I did a little more research behind this cuz I was thinking the same thing- it turns out that even though oxygen is more electronegative than sulfur, sulfur is much larger due to periodic trends. This large size allows it to spread out the negative charge better making it more STABLE. I think the key is to think which atom is more stable with the negative charge, not which atom is more likely to have the negative charge. In other words, when comparing elements in the SAME COLUMN (like O and S) look at its ability to stabilize the charge rather than just electronegativity - the greater the size of the atom, the more stable it will be with the charge. On the other hand, when looking at elements in the SAME ROW (ex. C vs O) you can just use your electronegativity trends cuz elements in the same row are roughly the same size- hope this helped :)
hi, i know i'm late, but i really hope you see this. 'bigger atoms have more s-character'- is that because sulphur has 3s subshell while oxygen doesn't?
it is depended on number of Carbon atoms it's surrounded by, if it is surrounded by 1-C atom, then it's primary, if it's surrounded by 2-C atoms then it's secondary and if it's surrounded by 3-C atoms then it's tertiary. thankyou have a beautiful day
Is it possible for an element in a resonance structure/form to have missing electrons but the rest of the elements have complete octets? I'm really really confused right now.
The positive charges are jumping because as shown in the first example, the pi bond is becoming a single bond, basically “losing” a bond, giving it a positive charge since they’re essentially opposite (when a bond is lost it’s positive, when a bond is gained it’s negative). Hope i explained that accurately I'm learning too :)

This channel has taught me that it is possible to not attend a single lecture and learn everything you need to know for the midterm in one day.
Your videos are helping me to learn chemistry keep the good work
This is golden material. I just appreciate this channel so much.. amazing quality
Thank you so much for what you do. These videos are a huge help in understanding these concepts.
Oo man thank you ve saved my life from failing chemistry may god bless you ❤️
Your intellect has never ceased to amaze me.
Really helpful video! Lots of examples to understand whats happening!
gang that study for tests just the day before it where u at
me rn with my chem exam
thank you so much for your videos , I can understand the book of chemistry but after your videos is like everything comes together and makes sense
9:53 - My professor said the most electronegative atom should have the negative charge as it is more stable, and if I am not wrong Oxygen is more electronegative than Sulfur so why is the negative charge placed on the Sulfur atom.
I agree. I’d rather listen to my professor ngl
It is because sulfur is bigger than oxygen. It is one of the few exceptions.
When going down ie top to bottom of periodic table we depend on size factor. So here, Sulphur is bigger in size than oxygen and so a negative charge on it would be more stable. (If you go period wise in periodic table ie horizontally then electronegativity is a factor which helps in comparing. )
The sulphur atom has vacant d orbitals within which the electron can move freely , thus causing stability of the negative charge over it
May God continue to bless you, you really have helped a lot of life
I am from India. I have found this video very useful. Thanks a lot for your struggles.
This guy deserves some pay..
3:33 can someone pls explan why 3 tertiary is most stable here ?
The electron donating R groups (in this case methyls but think of all alkyl groups as electron donating) stabilize the positive charge on the carbon. The greater the substitution, the more stable the carbocation.

Taking organic in 2 weeks definitely need a lot of review to make it through this.
@9:37 oxygen is more electron neg than sulfur, so wouldn't the major contributor be the structure where the neg charge is on the oxygen, not sulfur...?
Electronegativity is the tendency to attract shared pair of electrons to itself. Oxygen is an acceptor, not a contributor.
Sulphur has larges size

@@winterflower4530 yes
@@winterflower4530 thank you!!!
9:19 it's because 2s2 is closer to the nucleus than 2p2, and the more s-character, the more stable.. bigger atoms have more s-character
hi, i know i'm late, but i really hope you see this. 'bigger atoms have more s-character'- is that because sulphur has 3s subshell while oxygen doesn't?
how can you determine if it's primary, secondary, or tertiary?
A Carbon that is bonded to a single Carbon is primary. A Carbon that is bonded to two Carbons is secondary, and a carbon bonded to three is tertiary.
@@chase1064 specifically the carbon with the + charge i think
it is depended on number of Carbon atoms it's surrounded by, if it is surrounded by 1-C atom, then it's primary, if it's surrounded by 2-C atoms then it's secondary and if it's surrounded by 3-C atoms then it's tertiary. thankyou have a beautiful day

for real thank you so much you saved my future because the professor in school he couldn't make it as understandable as you
For those of u who r studying, tertiary carbocation is the most stable carbocation
I love you. You saved my life
Why isn’t the bottom left at 6:05 tertiary?
2:47 why is the positive charge there? isn't there 4 bonds at that corner so the formal charge is 0? I'm assuming hydrogen is there
my exam is today 🛐 thanks!
Thanks for this video🙏🏻
It's worth to watch your videoes thankyou
GIVE HIM A DIAMOND BUTTON ALREADY!!!!!!!!!!!!!!!!!!!!!
i hate resonance its been watching hours of videos and i still dont get it
Same here dude! Hope you got it now tho, pls help 😭🙏
man all of our tuition money shall go to this channel and not our profs
God Bless you, did not pay attention last lecture HGAHA
excellent explanation! thank you!
Upload more videos about chemistry bro and how to use integration in Physics then why to use calculus
Your videos are the best, thanks
What happened to 10:53 oxygen makes three bonds?
How are we deciding which number to rank the structures? What are we basing it off of?
thanks, I learned stuff
King boss tumas Tutor🙏🙏🙏
Please some questions on resonance
Thank You For This Awesome Video..!!!!😊
6:04 how do we tell if something is secondary or primary?
tertiary is liked to 3 carbons, secondary 2 carbons and primary 1 carbon
@@mariah-ql3qv in the same structure i think there is one more possibility of resonance structure . Correct me if im wrong
I’m waiting for this.
9:35 can it be explained as fajan'd rule?
Due to breaking of aromaticity, the “primary” cationic structure is the major resonance contributor for the benzylic cation
I was thinking this 2
Big thanks ♥️
Great lesson
Hi, please I want to know if there is a formula for calculating how many resonance structures there could be in a given organic compound?
I'm sorry but there isn't.
İsn't third one 3° carbin in 5.56 example?
4:28 why doesn't the carbocation have a lone pair? i thought if there is not enough bonds, you would have a lone pair instead.
If it had a lone pair, it would have a negative formal charge.
@@paysonkeown2960what is a fprmal charhe
How about the distance formula
What do you mean by common and uncommon resonance structures?
How do you determine which is primary, secondary, or tertiary?
i don't understand it either. Hope someone can help ^^
count the number of substituents hung on the carbocation. 1 carbocations are bounded to one carbon, secondary to 2 and tertiary to 3
@@sanafakih3541 thank you
Thank you so very much :)
wish me luck on my chem exam tomorrow
Hope it went well, mine is tomorrow
@Ash hope it went well!!!
Why oxygen has a formal charge of plus one. Yes it donates one lone pair to form a π bond with C but it doesn't lose any electrons
why couldn't the middle carbon gain a lone pair as part of resonance on the first molecule?
Wait whats the difference between the primary, secondary, and tertiary?
for 6:06 I got 4 resonance structures instead of 3, what did I do wrong😭
Identical structure
@@fmgtruefriend1335 what identical??
I remember when everything he'd post used to be free... Used to be a man of the people... Can't blame him tho
why did it turn two carbons towards the pi bond
Is it possible for an element in a resonance structure/form to have missing electrons but the rest of the elements have complete octets? I'm really really confused right now.
I believe the carbon can be short
