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.

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
Жыл бұрын
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

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
5 ай бұрын
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

Thank you for your useful video! 🙏 Can I ask please which is more stable a tertiary carbocation or benzylic carbocation or allylic carbocation?
@Leah4sci
Жыл бұрын
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
