EWG or EDG Trick Follow Up!

The EDG/EWG trick works great for some groups, but what about the halogens? And what about the nitroso group that my awesome viewers pointed out? Dr. KP follows up to explain the EWG/EDG trends in a few more groups!

[@dr_abhi14]

I had this confusion about EWG and EDG for almost a year and a half. I have a weak-ish foundation in chem (my school teacher's no good). These two videos really helped out. Thanks, Molecular Memory.

[@MolecularMemory]

Glad it helped! Thank you for watching!

I am very well fascinated with this video and the previous one. It is a concise trick that helps in understanding reactions of aromatic compounds. Please make more of these videos... Thank you.

[@aakritichaudhry1172]

After watching these videos I finally understand this topic, thank you!!!

[@sunghwancho9071]

thank you so much for teaching, I understand finally what is EWG, EDG even though I'm an graduate student....lol I was so so confused with this...

[@anjanapriyakonapala6992]

Before watching this video, I thought EDG and EWG are something that you have to remember and there is nothing such as a mechanism of how they work(at least that's what my chem lecturer said). I am really thankful for the clarification and your time to make a follow-up video on this.

It helped me revise this stuff and understand why X is deactivating.

[@msreyes04]

Thanks for the great videos, you explain things concisely and you also have a great speaking voice and inflection, which I find is one of the biggest factors in determining whether I actually pay attention to a video or not 😅 please continue making videos!

I remember very well :) We've put my tool in an upcoming Crash Course Organic Chemistry episode, and this time I was ready with that example! Thank you again for watching and leaving me a comment. Cheers!

[@michealdumasii5432]

Any updates on the strengths of EWG and EDG?

[@DeepakVishwakarma-vh7di]

Mam plz make a video on acidity ,basicity,and stability of organic compounds

[@MolecularMemory]

Here's one I made a couple months ago. Thanks for watching! kzbin.info/www/bejne/ZnKWeqOvfr6hsLM

[@indian2153]

But what if alkyl group is attached to benzene ring and halogen is attached to the same ring in meta position ? Is it will be o,p directing or m directing

[@jinbaofan8957]

thank you so much!!!! you saved my exam!!!!!!!!!!!!

[@MolecularMemory]

Yes!!! Great to hear. Thank you for watching!

[@imranashaheen77]

Why i didn't find this video early?.😏 Thanks alot.

[@iamDBK]

thank u so much. i just wanted to know one more thing, does ur trick work for compounds that are not bonded to a benzene ring but to straight chain(like butane or bentane)?..hope u reply. thanks

[@MolecularMemory]

Hi there! The group will be an electron donating group or an electron withdrawing group, regardless of what it is attached to. With benzene, the attached group is REALLY important, since it directs where the EAS reaction will take place, and that's why that's the topic of this video. But a nitro group will always be an EWG, no matter what it is bonded to. Thanks for the question!

[@iamDBK]

@@MolecularMemory thank you.....but what about the groups other than nitro groups.....can I use your trick for such groups when they are directly bonded to a straight chain?

[@MolecularMemory]

Daivik Bijoy yes nitro was just an example

[@anudeeparavapalli8469]

Mam what about -CHO, -COOH are that EWG or ERG

[@MolecularMemory]

These are EWG-check out the Part 1 video for the explanation! kzbin.info/www/bejne/r3bGZ6KsbpVniZY

[@daredevil9467]

Why halogens are electron withdrawing groups ? Although we know that resonance predominantes inductive effect. So it should be electron donating grp

[@Padmashrinaren]

They are electron donating due to the +M effect (resonance) but due to their significant inductive effect,they decativate the ring ! Pretty fascinating :)

[@parnika1511]

What about -NH2 group? Edg or ewg?

[@pratyushparmar1892]

electron donating group

[@saidchammas]

how about Ph-NO2 ?

[@saidchammas]

Also, can you make a video about R+ , R- , I+ , I- and how to compare stability/reactivity of compounds? Thanks!!

[@user-uv2wp9ir4d]

I want to meet professor who like Molecular Memory

[@himashreedesai]

Nitroso is meta directing and not ortho para directing!!!

[@MolecularMemory]

Hi there! Thanks for watching! My reference for this reaction is linked in this comment-it's from the text Science of Synthesis. I have only found this one example and I'm curious if you have a different source you could share with me that says something different.
