Electrophilic Aromatic Substitution reactions are one of the more fun topics that you will study in Organic Chemistry. But perhaps you find it tricky due to the sheer volume of information that makes up the big picture. And so, in addition to my EAS Tutorial Video Series I've put together a thorough EAS cheat sheet. Click the image for a high resolution copy, and print one each for your textbooks and notebooks.
The cheat sheet took a few hours to complete, and so I would appreciate if you click the social sharing buttons above to show your appreciation (assuming you find it helpful of course 😉
Enjoy
“thank you” is the least of what you deserve ..your are brilliant
Thanks a lot for sharing it.. I find it very helpful..
Please ma’am send organic books…..

It is really helpful a I shared with my college buddy!!
thank you so much,greetings from turkey!!
The moment I stumbled upon your first tutorial in orgo-1. I confess I always fail to use any other tutor, even class feels boring. You have been a savior to me and my friends throughout our orgo-courses. Thanks
ALL THESE STUFF WAS REALLY HELPFUL 4 ME…THANK U..SHARE MORE LIKE THESE..
thank you so much Leah.
very useful. Thanks
Thanks so much! Any way to get this in a pdf?
What does the O/M/P Monster say? Ch O-M-P!! I can’t get this out of my head now!
HAHAHA that’s awesome Bianca! Never thought of that!
Those are the things about your videos that always brings me back for more.
Its awesome and very helpful.. Thanks a lot.. Sharing it right away 🙂
You’re welcome! I’m happy to help!
Perfect! Thanks so much! I was pretty sure I was going to flunk my org test,this is a lifesaver!
awesome! glad to help you pass your exam. Good luck!
The two structures you show for the acylium cation ([RCO]+, used in the Friedel-Crafts acylation reaction) on the cheat sheet are not resonance structures. The R-C-O bond angle changes, and thus the hybridization of the C-atom, on the leftmost structure has changed between the two structures, and therefore the relationship between the two structures is not one of resonance (where only electrons move). The correct C=O resonance structure is linear, not bent as shown. You are also missing the two O-atom lone pairs on the leftmost structure.
More importantly, the C=O resonance structure does not contribute in any meaningful way to the overall resonance hybrid of the acylium cation. By far the major contributor (>90{4de72ea05502f43f582be05109791d04c2e06ba4d55e604218cbe1ea315cd788}) is the resonance structure with a C-O triple bond and a formal positive charge on the O-atom (the structure you drew on the right). In fact, the C=O resonance structure is not even the 2nd most important resonance contributor! Many organic chem textbooks and online resources misrepresent the resonance structures of the acylium cation, so beware!
This really helps! I shared with my study buddies
Thank you for sharing Janet. Glad it’s helping. Are you in a summer orgo course?
Great sheet …..but please show me how to remove that sticker tupe of thing on top
If you mean the red title just click the image for the full cheat sheet
Amazing!!! THANKS FOR YOUR BIG HELP!!!! I will surely pass this subject because of you.
Glad to hear that Pat. When is your exam?
AMAZING!! It is missing some reactions, but still helpful
Thanks Brittany. I chose to focus on the most common reactions for this. Which additional reactions were you looking for?
