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!!
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!
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...
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
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/
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
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
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 RU-vid comments. For help with this and more, I recommend joining the organic chemistry study hall. Full details: leah4sci.com/join
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 RU-vid 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/
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
Everything you need to know about Carbocation Stability and Ranking can be found in my multimedia tutorial at Leah4sci.com/Carbocation For further questions, feel free to reach out at Leah4sci.com/contact or join my Organic Chemistry Study Hall. Details: Leah4sci.com/join
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
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
