    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. :)

    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.

    Can I ask please which is more stable a tertiary carbocation or benzylic carbocation or allylic carbocation?

    • @Leah4sci
      @Leah4sci  Рік тому +1

      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?

    • @Leah4sci
      @Leah4sci  10 місяців тому

      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

      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

    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.

    • @Leah4sci
      @Leah4sci  2 роки тому +1

      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
