Wow, I just cannot believe how you explained the same topic as my teacher, but instead of taking 2 hours, you only took 16 minutes and I ACTUALLY got interested and learned.
You have really made my way of learning organic chemistry a breeze for my university class. You make everything more simplified so that I can understand the basic in order to move onto harder topics. Thank you so much!
I have been watching your videos like crazy. This year I plan on mastering organic chemistry, and dominating the ACS and Organic chemistry section of the M-CAT!!!
Para-director? More like (you are a) perfect-director (of our learning)! But seriously, I've seen a lot of positive comments on TH-cam videos before, but never to this degree. I am thankful as are all the other commenters that I can see, and keep up your amazing work!
HE DONT MISS!!!!! you actually make things understandable i cannot say enough thanks. Got me a 80 on Orgo 1 final. Orgo 2 was kicking my ass until now. GOAT!!!!!!!!!
It’s called Resonance, its a OChem1 Topic if you’d like to go back. Essentially its just saying that your electrons can move if theres enough aligned pi orbitals.
Hi, You have excellent teaching skills. I watched many videos of chemistry. Thank you. Could you please add more videos for the disconnection approach and retrosynthesis of organic compounds? This my kind request. Please consider my request.
hey man, at roughly 3:15 you say these groups are moderately activated and then you say they are ortho para. Then at roughly 13:00 you say moderately deactivated prefer meta. However the molecules look veryyyy similar. Can you explain?
It's all depends on which atom is bonded to the benzene. The ester at 3:15 has the oxygen directly bonded to the benzene ring, thus it is a moderately activating group because oxygen has a lone pair and can donate electrons to the ring by resonance. The ester at 13:00 has the carbonyl carbon bonded to the benzene ring, NOT the oxygen, thus it is a moderately deactivating group because the carbonyl carbon has a partial positive charge and withdraws electrons by resonance.
Just remember this. Lone pairs - activators and o/p directors. Double bonds mean deactivators and meta directors. Halogens are also deactivators that o/p direct but they are an exception.
Can I ask if I have a NH2 group in the para position to an ester group (for example benzocaine) would the NH2 group increase the rate of hydrolysis for the ester?
The para intermediate tertiary carbocation the electrophile attached carbon already had 5 bonds if we draw double bond at this position it becomes six how is it possible or by mistake
The people you are putting through college will flood your gates with gifts. Atleast I will to show my apprectiation. Lol If we could see your face you would be famous.
if already two groups are present in the ring? Sir! please discus about the third group entry in bi-substituted ring! Nobody interested to talk about that.

I had JEE main in April and you saved my 8 marks man ... much thanks 🎉
Hlo man how many marks did you score plz reply me I'm curious cause I'm also preparing for jee mains through this channel
I had no idea what any of this meant before I watched this video. Now I fully understand! You're a lifesaver!!!

How could the explanation be so clear like this!
You are making my 11th exams very easy, especially when it is hard for us to learn online during this pandemic.
This video is the biggest gain for me, i am from India 🙏
HE DONT MISS!!!!! you actually make things understandable i cannot say enough thanks. Got me a 80 on Orgo 1 final. Orgo 2 was kicking my ass until now. GOAT!!!!!!!!!
I just accepted what was an ortho/para director but this actually explains why! Thanks!
This also explains why certain substituents on the benzene make it more or less acidic. Thank you!!
What a relief ❤
I have a test in two days and I couldn't understand this part from my professor . Thank you so much ❤
i thought this topic was so complicated until i watched your video thanks king you always deliver
Oh my fucking god this couldn’t have been posted at a better time I’ve been studying this
Can always be rest assured when I'm on your channel. Understanding made simple!
You always have answers to my unanswered questions, thank you so much!!
This guy's actually the GOAT
Thank you so much sir❤️❤️❤️❤️... The way you teach is simply mind boggling❤️❤️❤️❤️.... Your biggest supporter.❤️❤️❤️
EXACTLY what I needed.
Keep them coming! Orgo 2 final is in a few days. Really appreciate that you are making more of these 😊
the best explanation! Love from India :D
Fantastic explanation thank you!!!
was so happy after watching this. thats all im going to say and THANK YOU ! God bless you
Thanks from INDIA🇮🇳 🙏
This is very best way I Am very happy after listening this
This was way more helpful than I was anticipating! Thank you.
at 8:00 , why did you move the double bond 2 carbons? shouldn't the double bonds be parallel?
It’s called Resonance, its a OChem1 Topic if you’d like to go back. Essentially its just saying that your electrons can move if theres enough aligned pi orbitals.
Thanks for all your hard work and time.
This is very helpful.. From Tanzania
Thanks for this video it really helped me a lot
I wish i had found it years ago .
Thanks, you really made this look easy.
bro you saved my life !!!!!!!!
YOU'RE GOLD, THANK YOU THANK YOU
Very helpful, thank you so much!!
Thankyou for makingg our concepts strong ❤
Man...You are the man... Thank you.
❤️❤️. God bless you Sir
I CANNOT THANK YOU ENOUGH
I Appreciate your work bro
Tysm, that was so helpful 💜💜
ارميييي
@@wandererrrrrr نعم😂
It's very helpful. Thanks a lot
very great content man keep it up !!
u r LEGENDARY...
Thank you once again.
You're so smart. Unf... I don't know what you look like, but doesn't matter... You're HAWT!!!
Google it , there's 1 picture of him up
His face doesn't look as I imagined though 😂
thank you for this!!!
I nearly cried when I c this video, cause I was confused by my professor yesterday
Thank you so much
Fantastic Video!
Thank you organic chemistry tutor for helping me find my way through the organic chemistry jungle 💯😂❤️
Thanks! ❤️
muchas gracias deeply thankful!!!!
thank you so much for your video, as usual very clear and helpful !
thanks mate! great explanation on nucleophilic and electrophilic nature of ortho and para carbon
Wow, you have helped me a lot.
Hi, You have excellent teaching skills. I watched many videos of chemistry. Thank you. Could you please add more videos for the disconnection approach and retrosynthesis of organic compounds? This my kind request. Please consider my request.
I'm in love with this man. I said what I said.
u r great sir
good lecture
on behalf of all Zambian students...
"we couldn't have done it without you"
8:37 shouldn't the double bond on the third molecule be on the right, symmetrical to the other one???
8:20 is wrong no the double bond doesn’t go there ?
my saviour.
Thank you sir.This video is really helpful.
Thank you for this great video!! For the CH3 group, since it makes the ring more electrophilic, why it is an activator?
wait... at 08:10 why did you put the double bond connecting to the electrophile at C-3 to C-4 instead of adding it to the single bond at C-2 to C-3?
That was the next resonating structure
thank you.
Thank you!
at 8:06 shouldn't the double bond go in between the 2 & 3 carbond if you're counting from the methyl group?
Thank you sir , may Allah bless you :)
hey man, at roughly 3:15 you say these groups are moderately activated and then you say they are ortho para. Then at roughly 13:00 you say moderately deactivated prefer meta. However the molecules look veryyyy similar. Can you explain?

@@aenseidhe-93 thanks for this Sir! This is extremely helpful
Show all the reaction mechanism while stating the type of the mechanism involved
Can I ask if I have a NH2 group in the para position to an ester group (for example benzocaine) would the NH2 group increase the rate of hydrolysis for the ester?
The para intermediate tertiary carbocation the electrophile attached carbon already had 5 bonds if we draw double bond at this position it becomes six how is it possible or by mistake
How does the withdrawing effect of e from benzene occurs by Br.
My exam is in the next two hours 😭
Is this the same for nucleophilic and electrophilic or does it change?
But isnt ester a deactivating group
Depends on the direction of attachment. If it’s (C6H5)-O-(COR) it’s activating.
If it’s (C6H5)-CO(OR) it’s deactivating

i love you
I didn’t get in 8:10 min
I love you
hey
OH has a formal charge of 0 right ?
6-(1+5) why does it even attack the benzene ring ?
I️ love you dad
I no understand ooo
