EAS Series: Video 1
The topic of EAS or Electrophilic Aromatic Substitution reactions is one that covers a key reaction pathways studied in the average organic chemistry course.
While the mechanism undergoes a broken pi bond and addition to the former sp2 carbon atom, the EAS reaction is very very different from the Alkene Addition Reactions you've studied back in Orgo 1.
- Benzene is much less reactive than the alkene's nucleophilic pi bonds
- EAS requires a super-electrophile which is more positive/unstable compared to the standard electrophile
- The pi bond and aromaticity is restored in EAS reactions
The video below will give you a quick introduction to the EAS reaction. Also, you will see a comparison to the alkene addition reaction and explanation of the super-electropohile.

you are the best !!!!!!!!! i
Damn I love you, you have helped me so much! I am taking orgo 2 right now and you have opened my eyes to all these little tricks which are helping me pick up on things i was struggling with! Thank you so much!

Ur the best! You have covered all the topics for my coming orgo exam.. A billion thanks to u!
you’re a life saver!
Glad to help!
I love you saved my life haha
Glad to help. are you taking a summer orgo course Mjay?
you’re making organic chemistry very simple
glad to know this is helping you. Are you in a summer course or finishing your spring semester?
This is great thank you a lot
You’re welcome Saran
You’re welcome. Which topics are you studying right now?
Thank you so much for those kind words and I’m really glad I was able to help you get through orgo 1 with confidence. Are you working on a summer Orgo 2 course or preparing for the Fall?
