Meta Directing Electron Withdrawing Deactivators in EAS vid 12 by Leah Fisch

[@AmazingMusicalArts]

This is one of the best explanations of activators and deactivators I have ever seen. Thank you so much!

[@Leah4sci]

You're very welcome!

[@itskeyanna8003]

why is this video sooooo helpful. thank you so much Leah.

[@Leah4sci]

Glad it was helpful!

[@lock152]

This was quite helpful. Im doin my end semester exam in medical chemistry next week.

[@lock152]

Thank You Leah for asking!!! I got a 4 GPA out of 5 it went great. Thank you loads.. keep up the good work

[@Leah4sci]

WOOHOO that's fantastic to hear!

[@CJ-km8ej]

[@Leah4sci]

You are most welcome :)

[@sandypark7776]

You are literally the best

[@sandypark7776]

I am a pharmacy student in Italy, and I am just amazed by how you teach the concepts that can be difficult in a very efficient and easy way while delivering the important points at the same time. I always study prior to watching your videos myself, then watch your videos. Then everything just clicks well and makes so much sense. I just wanted to say how I have been loving your contents!

[@Leah4sci]

Oh wow, thanks so much! I'm so happy to help clear things up for you and help you reach your goals!

You are welcome!

[@mansi.sharma29]

great explanation thanks!

[@Leah4sci]

You're welcome!

"...less in-your-face type reaction...."😂

[@Leah4sci]

Give them human characteristics and you're more likely to remember

[@alaamohamad3908]

Thank you very much

[@Leah4sci]

You're very welcome!

[@jayprakashjaiswal4369]

Awesome mam

[@Leah4sci]

Thank you!

[@andreachenshawol]

You’re the best!!

[@Leah4sci]

Thanks :)

Please explain why phenyl cation is not stable by resonance?? Since resonance structures are possible

[@Leah4sci]

First to confirm, you mean a benzyl carbocation which is a 'phenyl group' with a carbocation on the benezene's methyl substituent? If yes, it is indeed a stable carbocation due to having a total of 4 resonance structures

[@NikhilSharma-hv8dd]

Tq so much mam

[@Leah4sci]

You're very much welcome :)

[@ogeredmon6665]

Wow u are great

[@Leah4sci]

Thanks!

How to compare between the deactivators

[@Leah4sci]

What specifically is your question?

[@niroos6819]

🔥🔥🔥

[@Leah4sci]

😀

[@dr.aneesabbas6619]

nice madam

[@Leah4sci]

Thanks a lot!

[@Youtuber-dg9fo]

which one is an activator and which is deactivator.....how do i know them??

[@m.abdulahad7953]

If the substitute specie has electron donating nature(negative or partialy negative) the its an activator and vise versae!!

[@Leah4sci]

I cover that in detail in my activating and deactivating group videos here: leah4sci.com/eas

[@eliefant6353]

if it's meta deactivating then why isn't it in the meta position? I don't get it

[@Leah4sci]

at which point in the video?

[@minapasha]

nh3 is activator ??

[@m.abdulahad7953]

mina pasha yup cause it has a lone pair which will be donated during activation

[@Leah4sci]

Since NH3 as a substituent has a positive charge, it is an electron withdrawing group EWG and makes the ring less likely to want to adopt a positive sigma complex. This makes it a deactivator
