Shouldn't the carbon on the structure with 4 resonances be sp3 rather than sp2? Around the 10 minute mark?
Hello Leah!! Thanks so much for all your hard work and incredible content. I have a question unrelated to Orgo. What technology do you use to write all these lessons and project them on the screen? Are you using a tablet of some sort?
Hi Can i name the secbutyl -isobutyl
Thank you for the videos. I’m getting much much help from you! Btw I just have q question. 10:45 On the 4 th resonance molecule, Why the black electrons stop moving to the right side and the red electrons going back to the oxygen? Why it doesn’t have 5 resonance?
Thank you very much. Your explanation is very clear🎉
Thank you ❤ from Algeria 🇩🇿🫂
But sulfur crossed the octet rule, it has total 12 electrons now 😢
To make it more simple, is it okay to swap only once, and think it is the opposite direction? Ex. I swapped once, and became S. Then it is R!
I wrote my final exam in organic chemistry just wanted to say thank you for making it bearable
God bless you and grants you more wisdom
You made it really good video, I don’t like this chapter but with our video I’m starting to understand 🌷, I still have a question : when an acid is weak (and therefore stable) it still reacts with au to give its conjugate base And even if it reacts with water because even if it is weak it still gives its H+ Why does its conjugate base, which is strong and therefore unstable, not re-react with an H+ to regain its stability (why does it continue to exist) Why is there an equilibrium when a weak acid reacts with water whereas normally its conjugate base which will be unstable will have to reform the acid
Love ur vids omg
I love my professor for the rest of the topics... but he wasnt so good at explaining the reactiojs part 😢 Thank❤ you
Orgo 2
Hope your class is going well
Thanks!
1:15 why Br is attacking back.
Br is an electronegative atom, when the pi bond attacks, the carbon no longer holding the pi bond is now left deficient and therefor positive. The electronegative Br is attracted to it and therefor attacks
@@Leah4sci Thank you..
Excellent ❤❤❤❤❤
thank you leah you've made me understand what i've been struggling with my exam is tomorrow
Even after 3 years , this video proves to be very very useful ❤
Thanks
Will someone please make a video on azidation of alcohols. Even in my text books it's not there
I'm not familiar with the reaction
Thank you ❤
Thank you for your tutorial
Just amazing. Best video on whole UA-cam for acid derivative and their Interconversions.
Wow! I'm mindblown!
Very helpfull mam
Why does H30+ donate an OH group and not just an H?
organic chemistry tutor officially has a run for his money
I love your videos
Thank you so much, you're the best fr😊
you deserve 8475937532 likes. You're an amazing teacher. Send you billions of hugs hahaha <3 Thank you sm
You are simply the best m'am .Do you have any lecture on dash wedge nomenclature of organic compounds,I'd look forward seeing it.Thank you very much 🖤
The direction of the arrow in the video at time 3:26 is clockwise. If I reverse the direction to counterclockwise but the final product remains the same, does it mean I am representing the mechanism incorrectly (i would love to know)
It's a cyclic mechanism which means the electrons are all moving at the same time. No, it wouldn't be wrong
i like your teaching style and color-coding, I appreciate your time to make this video
Thank you so much, glad it's helping
nice
Thanks
Thanks!
Aww thank you so much! I really appreciate it! this is going right back into the channel as I'm currently working on plans for new Fall semester videos
Honestly never once liked these overview videos but this one is an exception. Amazing explanation and cheat sheet. Truly helpful!
I'm honored that this video is an exception for you. So glad you gave it a chance and found it helpful.
I'm watching these as I'm going to uni for chem:) these qre amazing. I wish I listened to my ap chem teacher's advice of wqtching these for chem olympiad
Extremely helpful, giving me the chance to practice for my licensure exam.
Thanks
You're very welcome
❤❤❤

"when oxygen yanked off the electrons binding it to carbon, IT LEFT"😂just kills me. you made it sound like oxygen was tired of the relationship
hahaha when trying to understand mechanisms, give the atoms human characteristics and you'll realize organic chemistry is more exciting than any soap opera
You're an Angel ¡¡¡
Thank you!
I’m a little confused by the comparison of -oh, -nh2, -ch3 example. If we lose their Hs to give them a charge, and o is more e-neg, shouldn’t it be most stable and less reactive. Also, we said the more positive was the acid so shouldn’t that be the carbon?
You are right in that the more electronegative the more stable it will be with that negative charge. But don't stop there Once you determine that a conjugate base is stable, you can infer that the acid forming said conjugate base is most likely to react knowing the product is not dreaded/unstable. the more stable the conjugate base, the faster the acid gives up a proton, the MORE reactive / more acidic the starting acid. hope this helps
Can you do one for Condensation reactions of aldehydes and ketones please
If you mean enolates I cover them here: leah4sci.com/enolate
You deserve it ❤❤
but why is the orange OH a singlett and not a triplett... arent dhe Hs on the CH2, two neighbours? minute 32
If you're asking about the alcohol's H, that's different. Since the H sits on oxygen the interaction between them is different compared to H on C and therefor will no split/be split by neighbors
