Intro to Conjugation and Allylic Charges

joechem.io/videos/21 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 talk about the concept of Conjugation--how to identify it, why its a stabilizing force, and much more. In addition, we talk about the allylic position, and how conjugation helps in stabilizing charges when they occur at an allylic position (hint, our friend resonance is back :) ).

I absolutely never comment on videos, but my man, you explained this 100 times better than any other video I've watched. Much appreciated.

[@jOeCHEM]

Ayoub, thanks for taking the time to comment 🤓 I really appreciate it & the kind words! If you're looking for any other videos (or practice), make sure to check out joechem.io for the same videos + the guided worksheets & solutions (also 100% free!).

[@LanceNightshade]

These videos single-handedly accomplished what textbooks, lectures, and other videos could not for me. Thanks for helping me connect the dots, even 5 years later.

[@isabellamina9039]

Thank you for your great explanation :) I like how I can feel your energy and passion for chemistry through the screen and it really motivates me to study

[@taninho_onthebeat]

You're making uni life easier, this was explained so nicely

[@tylerbradley8124]

thank you! studying for the DAT and all the other resources on this topic are extremely confusing! this really helped

[@ilaydamumcuoglu8339]

Such an amazing video, finally i understood conjugation

[@friedlemon5172]

this was very well explained, thank you!

[@wasimabdin9882]

Brother u are awesome it's far far far better than any other video

[@jessiedavid6399]

Thank you so much Joe! It was very helpful and provided me with such clarity. Love, ma'am

[@jOeCHEM]

Jessie! Thank you SO much for watching.

[@TheAlphaRadiors]

Thank you so much! Your teaching is absolutely amazing!

[@jOeCHEM]

[@pludo645]

Holy shit dude. You're amazing and you deserve a million subs! Learned it really quick and your SO much better than my prof!

[@jOeCHEM]

Sivasai! Thank you for the insanely kind words 🤓so glad you found this video helpful. If you want guided practice, make sure to check out my website as well joechem.io where you'll find all of the same videos + worksheets & solutions I've made to go along with each video (all for free!).

[@mariamata1029]

Thank you for saving my gpa. I hope you're doing good

[@jOeCHEM]

Maria! Thank you for the incredibly kind words, but YOU are saving your GPA because I can make 6.02E23 videos but you are the one watching them and putting in the work 🎉

[@kyra5783]

Posted six years ago and still better than last ed. of textbook at my library?! Watching these before class has been so helpful and made the new topics less intimating! Many thanks!

[@jOeCHEM]

@kyra5783 thank you SO much for the kind words! I'm so unbelievably pumped jOeCHEM is making OChem less scary (and hopefully fun!). In case you haven't checked out my website joechem.io, you'll find all the same videos with worksheets, solutions, videos of me doing the worksheets, and study guides (i'm still working on many of these). Thank you so much for being a jOeCHEMist! I'd super appreciate if you spread the word if someone you know may benefit from it too. Good luck this semester--you're going to crush it!

[@Badgerbahalwan]

wonderful as always🙏🏽

[@Amelia-dh1ot]

Joe, you saved my life

[@aliyachirapant1963]

bro thank you so much! so simple and helpful!

[@knyixx838]

Joe, you are absolutely underrated. I had the pleasure of having Dr. Huston for Ochem 1, and although she recommended your videos, I didn't watch them. It wasn't until now, when I am taking Ochem 2 with Dr. Bandik, that I understand why you were recommended (again). I didn't realize you also went to Pitt! I'm not sure who you had when you were taking Ochem, but the material should be more or less the same. I deeply regret not watching your videos when I was in ochem 1 because this video was a huge help, and I figured it would've helped me then. I am excited to learn more from your videos! If any of my friends have trouble with these classes, I'll direct them to your channel

[@jOeCHEM]

@knyixx, thank you for the super kind words ❤️ and yeah haha h2p always! So glad you're finding the videos helpful, and thank you for passing on the word! Very happy to have you as a jOeCHEMist!

[@gianegonzales2571]

Thank you so much! I understand it so much better now.

[@jOeCHEM]

giane gonzales hey Giane! I’m so glad the video helped :) Make sure to check out the worksheet that goes along with it (they’re linked on my actual website, check the description for the link), and if you have any friends taking Ochem that are looking for help/practice I would so appreciate it if you steer them towards my site/KZbin channel 🙂

[@ahmadabdullah8168]

This is so helpful, thank you!

[@jOeCHEM]

Thank you for watching, Ahmad! Make sure to check out the video on my actual website joechem.io/videos/21 to see the accompanying worksheet (with answers).

Thank you Joe

[@jOeCHEM]

Thank YOU, Rebecca

[@isabelokeke1649]

Wow you just explained hybridization that i have been trying to understand for ages and i didn't even come here for that topic lol

[@LegolasUpendra]

thank you! thank you! thank you!

[@zahrahabibi9196]

From Afghanistan Tnx teacher Greattttttt

[@prathvisingh8288]

Very nicely explained! I just have one small doubt. In the butadiene structure at 3:00, I understand that the p-orbitals of C1 & C2 carbon atoms are aligned with each other which makes the pie bond between them possible. But how can we be sure that the p-orbitals of C2 & C3 carbon atoms are also aligned with each other & not at right angles to each other?

[@nomfundo.educabilitysibamb528]

Thank you🙏

[@naderelsarrag]

thank you so much! i love this channel! quick question though. Are those charged carbons in the vinyl position? i thought vinyl would mean its 1 away right?

[@jOeCHEM]

Hey Nader! So great question, because using vinyl can honestly be can tricky. So allylic is the term you're looking for whenever you're referring to the carbon NEXT DOOR to a carbon that is part of a double bond (think the sp3 carbon in propene -- checkout 7:21 in the video kzbin.info/www/bejne/gKPZY32tateoiaM). Vinyl on the other hand refers to the collective group of both carbons IN THE DOUBLE BOND ITSELF when you have a ethylene substituent (aka when you have a branch that consists of 2 carbons and they are double bonded to one another). The allylic carbon is a position, where vinyl describes a group. Check this link out www.chem.ucla.edu/~harding/IGOC/V/vinyl_group.html I think it does a good job illustrating a vinyl group. Let me know if this makes sense or doesn't make sense! And thanks for watching :)

@@hadeerrashad5486 You. Are. THE BEST.

[@hadeerrashad5486]

jOeCHEM I’ll refer your videos to my friends!!

[@laucheukming5580]

Thanks a lot sir. I pretty sure that if you can talk more about the MO energy level digram explaining more how the electrons within the entire molecule, it will become more juicy!!!! The MO energy level diagram would be a little difference in allyl cation and allyl anion!!!

[@alderamin1402]

Thankssss

[@wejdan7430]

D.joe Who initiated you in organic chemistry please answer my question?

[@dhanushas9248]

Why the stability is directly proportional to no.of.resonance structures

[@jOeCHEM]

More resonance means that charge is distributed over a larger network of atoms, which is a stabilizing effect. It's always easier to lift a couch with more and more people vs just by yourself, so more resonance structure = more overall stability for that overall resonance hybrid. Does that make sense?

[@dhanushas9248]

Thank you sir. I am from India, tamilnadu

[@bouyi_sciences5116]

Sir i have a question

[@JaechelleB]

the solution for this videos worksheet is not posted correctly! the link takes you to conjugation #2s solutions - there is no solution key for conjugation #1 :'(

[@jOeCHEM]

Hi j!!! Thanks for pointing that out (that was a mistake on my end). You should be able to access the solution to the worksheet now (it's also linked here for you convenience: worksheets.joechem.io/worksheets/ANSWERS%20-%20Intro%20to%20Conjugated%20Systems%20and%20Allylic%20Charges) Also, I have videos where I go through the worksheets, so be sure to check those out as well: joechem.io/videos/wksht-soln-walkthrough/36

[@jOeCHEM]

Preju! Thank you for watching. Glad you found it helpful (:

[@MiriamOmer]

you look like a smart joey tribbiani from friends wtfffff

[@srulyappelbaum413]

Where's the worksheet?

[@jOeCHEM]

Sruly Appelbaum hi! So this is my own website (linked here): joechem.io/videos/21 This has all the videos and worksheets (worksheets linked below the video so you know which worksheet goes with which video). Everything on my site is free, and I will be updating descriptions on my KZbin videos, but I’m in the middle of moving everything from. Vimeo (where my videos are hosted currently) to KZbin. But go to jOeCHEM.io for a better user experience.

[@hassaanahmed23]

on a side note i can now say my chemsitry tutor is immensly cute

[@liangshuang5436]

whos Joe?

[@savvasavraam8670]

Is it weird? I talk to myself like that when i study but without a camera recording

[@jOeCHEM]

It can be--it's even worse when you forget to press record and then do a whole take lol.

[@isabellamina9039]

I do the same haha! It helps me memorize stuff

[@sibtainali7341]

you look like joey from friends

[@jOeCHEM]

Haha, I've actually gotten that for most of my life 😂

[@ashtonmeyer1580]

Cute and hot simultaneously...

[@jOeCHEM]

😂 thank you for the kind words and for watching!

[@zohaawan9310]

This is so helpful, thank you!

[@jOeCHEM]

Glad to hear! I'm unsure if you saw my reply comment on here as well, but if you want an accompanying worksheet go to this link and theres a worksheet with answers: joechem.io/videos/21 (joechem.io has videos and worksheets for ochem I and II)
