Struggling with Orgo? Grab my free ebook '10 Secrets To Acing Organic Chemistry' here: leah4sci.com/or...
In (this) video 3 of my Electrophilic Aromatic Substitution I take you through the aromatic halogenation mechanism from the role of the Lewis Acid catalyst and formation of the super-electrophile, through the entire mechanism of adding halogen to benzene.

7 years later and this is still incredibly useful, thanks a ton!

[@Leah4sci]

You're welcome!

[@PunmasterSTP]

Can confirm that it is still incredibly useful 8 years later!

[@RabanyMedo]

Can confirm it's still useful 10 years later!

You are literally heaven sent thank you for all you do for us. I realize how lecture isn't as helpful as KZbin. You are the best professor. This is my last semester of Ochem you have been the upmost helpful. May God bless you in ways you would never know. I wish you more success, recognition, and blessings to come your way.

[@Leah4sci]

Oh wow, thank you so much for your kind words. I'm happy to hear how much my resources helped you in organic chemistry!

[@PunmasterSTP]

I just came across your comment and was curious. How'd your last semester of Ochem go?

[@hannanojams3194]

i swear i love you. your explanation is so easy to understand

[@Leah4sci]

Aww, so glad to have helped!

[@watsoncrick6071]

You really made me love organic chemistry. So much thanks to you

[@Leah4sci]

Yes! My secret mission is complete!!! Seriously, glad you love it now!

[@yase672]

Your explanation way is GREAT. It is such a relief for an organic student to watch your videos... Love from Turkey

[@Leah4sci]

So glad it helped you!

[@niroos6819]

It was crystal clear I wonder why my Chem teacher can't teach like this thank u so much

[@Leah4sci]

Thank you for the kind words :). You are very much welcome. :)

[@roushangiri4722]

Gosh! I think that my professor's have bribed you. Cuz I didn't liked organic chemistry because its very confusing and all of time. I rather tried memorizing things that ended up in chaos during examination. But after watching your videos i have affection for organic chemistry! hehe. Thanks a lot for making organic chemistry so lucid.

[@shubhampuri8384]

So earlier, Organic was 'alkynes' of trouble... hmmm...

[@Leah4sci]

You're very welcome, and I'm so happy to hear that I helped you learn to love orgo!

[@sroshyaver1168]

Thank you for doing these EAS videos! They are awesome and they make it possible to actually understand Orgo as opposed to just memorizing for an exam.

[@PunmasterSTP]

Hey I know it's been half a decade, but I just came across your comment and was curious. How'd the rest of your orgo class go?

[@sroshyaver1168]

@@PunmasterSTP lol not great I'll be honest but that was due to a shift in priorities and future plans.

[@PunmasterSTP]

@@sroshyaver1168 I appreciate the honesty, and as long as you focused on higher priorities I think it's all good!

At 4:50 in the video, is the negative formal charge on aluminum motivating chlorine to break away from the AlCl3 catalyst and form a bond with hydrogen?

[@marcelopvargasb89]

This is awesome!! it was a clear and precise explanation!! thank you!!!

yay! So happy to hear this!

[@kosisochukwudon-adinuba141]

Does the explanation of ALCL3 work for fecl3 or febr3. I mean if I’m explaining the formation of the super electrophile using say cl3 &fecl3 can I also give the explanation of the fecl3 having empty p orbital that the cl2 will attack?

[@Leah4sci]

I'm sorry, but I don't offer tutoring over social media. For help with questions like this and more, I recommend joining the organic chemistry study hall. Details: leah4sci.com/join or contact me through my website leah4sci.com/contact/

[@gretawilliams8799]

You're great

[@Leah4sci]

Thank you

[@xerib]

could someone pls explain why aluminum has a free p orbital? since it gives his 3 valence electrons to chlor to have full octet, I don't understand where this free p orbital comes from and would be sooooo happy, if someone could help me with that

[@Leah4sci]

First, a free p orbital means an empty p orbital available to be filled with attacking electrons. If you remember in hybrid orbital theory, a molecule with a central atom like aluminum that forms 3 surrounding bonds is trigonal planar in shape, or sp2 hybridized. Those 3 bonds are formed by the overlap of sp2 hybrid orbitals. The sp2 hybrid orbital is made by the mixing of 1 atomic s orbital and 2 atomic p orbitals. Meaning, the third p orbital on the 3rd energy level of the Aluminum atom is empty and not participating in the hybrid orbitals that create the bonds of this structure.

[@Leah4sci]

For more on hybridization in organic molecules, make sure to see my Organic Chemistry Basics series at Leah4sci.com/OrgoBasics

@@Leah4sci omg thank you so much!!

[@yegonchristopher]

Great

[@Leah4sci]

thanks!

[@erussell57]

What is meant by MTP orbitals (Al)?

[@NCICBrooklyn]

I think she's saying empty P orbitals lol

[@Leah4sci]

At which specific point in the video? (timestamp please)

Okay, so I was hoping to get the reactions for aromatic reactions to learn and understand, but most of your videos are confusing and are mostly talk. Not helpful at all.....

[@Leah4sci]

I'm sorry you feel that way. My goal was not to waste your time, however I realize that while I try my best to explain, not every video will connect with every viewer (as much as I hope it does)
