Reactions with Conjugated Systems

joechem.io/videos/22 for video on jOeCHEM and attached worksheet + solution (below video on jOeCHEM aka the link).
Worksheet: worksheets.joechem.io/workshee...
Worksheet Solution: worksheets.joechem.io/workshee...
Worksheet Solution Walkthrough: joechem.io/videos/wksht-soln-...
Study Guide: (To be created, but Joe's working on it!)
In this video, we'll take our knowledge of Conjugation and see how Conjugated Systems behave in reactions that we've used in the past, such as Markovnikov Additions, Halogenation of a double bond, etc.

Yay for "the dope allylic one" @ 8.20. Made my day. Thank you for doing the 1,2 and 1,4 with a 6 Carbon molecule. It clarified a lot. Serious lightbulb moment on a concept that had been eluding me.

[@lienenomungole2916]

I can't thank you enough man , you're a blessing to humanity 🙏🙏

[@bigdripsausy1310]

🤧🤧🤧🤧 obsessed at this point, thanks a lot. ❤️

[@grettlowski]

Thank you for your explanations. And idk if you know this but you're a SNACK!

[@estelamemushi2943]

Wow i never understood orgo til now! Btw you look like joey from friends :)

[@jOeCHEM]

I'm glad this made sense, Estela! And that's so funny (the first time I got that was my kindergarten teacher telling my Mom that I looked like Joey). Also make sure to check out my actual website (joechem.io) where the same videos + guided worksheets & solutions are linked! And they're all FREE. Also if you'd subscribe, I'd massively appreciate it (if you haven't already).

You are a wow in chem lol

[@jOeCHEM]

Thank you!!!

For the first example, couldn't you also have products where the hydrogen attacks C4 (counting from the right) since that also produces an allylic carbocation which would then have another set of two resonance structures?

[@jOeCHEM]

Hi Sivasai! You're right--in that example, I didn't fully flush out all the products. I was more so explaining how you can get an array of products based on resonance. Make sure to also check out the follow up video to this one, which goes into thermodynamic and kinetic control for reactions kzbin.info/www/bejne/iHKrf6alZcyAhMk

@@jOeCHEM Gotchu. No worries! You already did an excellent job with the video!

[@suvangoyal4081]

why is the Chlorine atom splitting heterolytically? Even though the bond is non polar?

[@jOeCHEM]

Hi Suvan! A Cl-Cl bond is actually pretty brittle. For example, in Free Radical Halogenation, Cl-Cl bonds can heterolytically cleave when subjected to sunlight (the energy in sunlight is enough to do the job).
