You're an awesome teacher! But I think you have heard this before, a LOT! You make intricated and difficult seem simple, as a true teacher should do, because Organic Chemistry is complicated, but so are relationships, and we keep getting into them. Keep on with your attitude, it's the right one, and THANK YOU! You helped me a lot.
It took my professor three days to explain these concepts and I still didn't get it. I watched this video ONCE and completely understand it. You ma'am, are truly amazing. Thank you for your help!!
Blowing up your comment feed today, but you have a gift for making the basic concepts so much easier to understand!!! Having trouble downloading your ebook, though...
I'm reviewing some of my basic for the Mcat, I find that small questions pop up here and then and I really don't have the time to read deep into the text. your videos are perfect because I have 95 percent of the concept down it helps me complete the image in my head. many thanks!
excellent lecture mam each point is very clear.I have started tuition classes for ISC 11th students. your lecture is very heipful reference.iwould like to know the details of the other topics uploaded
You're welcome! This is a tough question. Some professors will rank a primary benzylic carbocation under or near a tertiary carbocation. And then the primary allylic carbocation is nearly equal to a primary benzylic, as well. If you have further substitution on either your allylic or benzylic carbocations, then their relative stability will increase accordingly. Make sure to read more about carbocation stability in my tutorial at Leah4sci.com/carbocation
what is a nucleophilic carbocation. Why are double bonds nucleophilic? Also, do allylic carbocation win over just mere primary, secondary, and tertiary structures
I'm sorry, but I don't offer tutoring over youtube comments. For help with this and more, I recommend joining the orgo study hall. Full details: leah4sci.com/join
I draw the resonance structures for a primary benzyl carbocation around 13:00 in this video. For further help with questions like this, I recommend joining the organic chemistry study hall. Details: leah4sci.com/join or contact me through my website leah4sci.com/contact/
Hi, what if our bounds for carbonation weren't all in the plane . I mean, we had forward and backward bounds for carbonation in tertiary form. Would it be stile the most sable too?
Tertiary carbocations are ALWAYS more stable than primary or secondary carbocations. Molecular geometry (shape) is not what contributes to its stability. Rather, it's about hyperconjugation. Carbocations are stabilized by having more neighboring groups. Make sure to take a look at my tutorial on this topic at Leah4sci.com/Carbocation
Leah4Sci, I'm getting ready for Ochem I and your videos have been great, Thank you! One question, if methyl and primary carbocations don't "form" as you say, why do we even learn them? What is their point? I assume they can "form" in very specific circumstances perhaps? Thanks!
I'm so glad to be of help! As for your question, I'm sorry, but I don't offer tutoring through UA-cam comments. For help with questions like this and more, I recommend you join the organic chemistry study hall. Details: leah4sci.com/join or contact me through my website leah4sci.com/contact/
Hello thank you very much for posting an educational video. I just have one question in mind, will the electronegetivity of the R groups effect the inductive effect or hyperconjugation in any way?
I'm sorry, but I don't offer tutoring through UA-cam comments. For help with this and more, I recommend joining the organic chemistry study hall. Full details: leah4sci.com/join
It depends on the substitution. If I'm not mistaken, primary benzylic is about as stable as tertiary, but secondary benzylic or higher is much more stable
It's too basic , can u please upload something where we can get to know the stability of carbonation of complicated systems leading to rearrangement, ring contractions and expansions
There are no lone electrons on these carbons. You'll see the electrons are contained in bonding pairs. These carbons are positively charged because of a LACK of electron density. They have less than a full octet. To learn more about calculating formal charge on individual atoms, see my tutorial at Leah4sci.com/Formal

You are so good at teaching Organic Chemistry. At this point, I don't even care about my grades. I'm just loving Organic Chemistry.
Wow, thank you! My secret mission to make you love orgo has succeeded!!! But I also want you to ace it, so go ahead and care about the grades, too. :)
This, along with literally every other Leah4Sci video in existence, is awesome. Thank you!
Thank you for your kind words! You're very welcome!
If only my professors could put in the effort that you have for these wonderful videos, thank you so much!
You're very welcome!
Honestly my favorite thing about your videos is how quick and straight to the point they are. You are awesome!!
So glad you liked it!

Wow, thanks so much for all your kind words, I really appreciate it! Glad I was able to help you when you were in orgo :)
Thank you drawing circle and dots to highlight the carbons. That small detail really helps
Glad I could help!
You're saving my hide this semester, and I seriously can't thank you enough! Wonderful videos, Leah!
You're very welcome, happy to help!
Leah Fisch you are my hero...Thank you so much i could practically listen to all your videos and go into the exam room feeling like a genius
Oh wow, thanks for your kind words! So glad I was able to be such a help for you!
Best Orgo videos on UA-cam by far.
Aww thank you so much!

THANK YOU SO MUCH!!! THIS IS THE VIDEO THAT FINALLY MADE IT CLICK. YOU’RE AMAZING.
You're very welcome! Glad I could help :)
I've been struggling with organic chemistry ☺️ finally i found the best teacher...i wish i had found earlier 💔 my exam is getting closer 💔

Ma'am so in total how many resonating structures are possible in primary benzyl carbocation.
Thank you ma'am
Lots of love from india.

Methyl carbocation And vinyl carbocation stability see by which factor mam??
I don't understand your question

nic and thanku for this video
you're so welcome!
Just curious, how many times a second does the resonance structure change?
great question! (no idea)
Thanks😃 .. i wish I could replace my school teachers with u..
You're very welcome!
Benzylic or tertiory more stable?
It depends on the substitution. If I'm not mistaken, primary benzylic is about as stable as tertiary, but secondary benzylic or higher is much more stable
Thnks ma'm
Good
Thanks
A goddess. You saved me
Happy to help!
What is an R group?
I cover this exact answer in my Functional Groups Guide, found at leah4sci.com/functional-groups-guide-organic-chemistry-drawing-naming/
good

Chemistry is weird, you would think a lone electron would have a negative charge, but in this case, it makes the charge of carbon positive.
There are no lone electrons on these carbons. You'll see the electrons are contained in bonding pairs. These carbons are positively charged because of a LACK of electron density. They have less than a full octet. To learn more about calculating formal charge on individual atoms, see my tutorial at Leah4sci.com/Formal

Why this video play without sound
The sound worked for me! Make sure your speakers are on and the volume is up
dang this video is from 2011 for realllll
It sure is!
where is the part two video?

God I hate chemistry
I'm sorry to hear that, but hope I was able to help!
Say properly in normal English plz we can't understand this type of english
Rude. She is brilliant and you are the only one who can't understand her.
um... what?
Very helpful, thanks!
