After 4 years also these lectures are goldmines to IIT-JEE students. Thank you very much.🎇🎇
Our motive is to educate all of you guy’s by delivery the best, tricky, short, simple & relevant material .✅🚀
Also for neet
It's 6th year
6* year😂
It's 7 years 😂
After 7 years,this lectures are gold now too
Who is here after 7 yrs 😮🤍??
8 yrs
Now for the first time I understood mesomeric effect
Thanks
Sir your teaching skills
And fluent and pleasant voice always
Clear my each and every doubt. ❤
Glad to hear that
Yes sir...
Sir, Can you please write the order of Conjugate system? means which is going to dominate more and which is less (in short order of dominating from highest to lowest).
I learn a lot from your videos sir even though I'm a teacher
Learning is a never ending process sir... No human on Earth has ever completely learned everything before leaving this Earth ☺️👍
And nice to see your attitude.... There are teachers who stay on cloud 9 but your down to earth attitude shows that your students might be very lucky to have a teacher like you ☺️❤️
V good u have a fighter and learning spirit ...

Thank you so much sir for this video...here, I cleared all my doubts related to mesomeric effect..nd your teaching skills is so perfect...!!
You are most welcome
After 7 years lec was super 🎉
Sir u people are doing a great job....we are blessed to have teachers like u who jst need their children to be studied and have a bright future....apart from your busy schedule u are uploading these video's it is commendable..... thanz a lot sir
Good video
AFTER 6 YEAR I AM WATCHING THIS
OMG KILLER CONCEPT VISUALISATION ❤️❤️❤️❤️❤️❤️❤️❤️
Thanks u so much sir 💓❤️😘💓❤️😘
Concept cleared
Thank you sir
In the second last example why did the flow was towards the group? Because it was π sigma π reso in both the places with carbon atom only.
In last question can we consider cojugation b/w lone pair of N and C=O
hence answer will be -M
Nilesh Singh O is more E.N.
Dushyant Gupta but it never base on electron negativity of the group
No because N would shift electron density more than what oxygen would do to carbon also the carbon would be partially stabilised by inductive effect hence nitrogen has more tendency to donate electron to carbon cation of benzene rather than of c=o
Thank you soo much sir 🙏💕 these are the concepts we once studied during 11th but now in college by watching your video for just 10 mins everything gets revised . Thank you so much you're doing great work
All the best
Same I am doing
V nice and time saving other you tubers should take inspiration from ur video in such a short period of time u have explained well
Sir I was fully confused when my sir gave hw yesterday but now it is full clarified thank u sir
You are welcome
thanks sir you know I am topper of my class in organic chemistry bcoz of u
😊😊
Cash Money delta positive due to doubly bonded oxygen atom
@Cash Money double bond => sp2 hybridization.
Single bond => sp3 hybridization.
Greater s-character => greater electronegativty. Thus double (or triple) bond C atom more electronegative than single bond C atom.
@Cash Money That oxygen really likes electrons, due to it's property of electronegativity... and what deuterium tritium wrote
in a class of 5 😂😂
Sir While discussing +M effect u said that lone pair of oxygen from OH will go in the Benzene ring by Resonance but in -M effect u said that O of NO2 will take electrons due to electronegativity.......
So why electrons are going away to carbon in the first case considering the fact that O is more electronegative than C ??
Any Time Padhai Academy Sir can you tell what will happen if an Isocyanide group is attached to the ring?
Harshvadan mihir +m effect
Any Time Padhai Academy
But I think sir, that resonance also depends on electronegativity...
In case of , benzaldehyde , the electron from the pi bonds between -CHO group are shifted or transferred to the oxygen atom because oxygen is more electronegative than carbon.
Rather due to this C=O is much more stable than C=C.
Thank you
Bruh , in this case OH shows +M and -I effect both , but note it down that +M dominates -I effect except halogens.
and whenever, O has double bond with an atom of less electronegativity, it withdraws the electron from the bond pair…,
hence it will show -M effect, as in benzaldehyde …
10 days left for JEE 2019 and this video is proving a lot helpful for my revision. Thank you sir!!!!
How was jee 2019 , i am preparing for jee 2020.
@@shreyankp1 how was your jee 2020, and which college are you in right now
Do u cleared ?
Means the atom attached to the ring is very important
Fabulous fantastic ❤ explained
Sir in the +M effect, cl is an electronegative atom so why will it show +M affect instead it should show -M affect
Inductive effect will dominate over mesomeric effect in case of halogens
Mesomeric>hyperconjugation>. Inductive effect this order u have to follow will choosing the ans
I have the same Q
Crystal clear thanks sir ❤️ coaching m ghanto ka lecture soonne k baad yha ake concept clear krta hu.
These lectures are proving us that the content is real gold 🪙🪙 they haven't lost their shine till now
Thank you sir I can't believe your team has posted my comment in the telegram community.
sir u teach best organic chemistry on youtube .... love ur videos sir ....
Thank you sir very very much i love your concept and teaching sir thanky you sir ❤️❤️
Most welcome
in the last example the third structure during the pi bond pi bond conjugation both ch grps have same en then y it moves towards the one which is not directly connected with benzene ring
Thanks sir for providing such awesome lessons with easy method I was able to score good marks in chemistry in my board exam because of you....
How to compare strength???
-OCH3 & -OH which is stronger (+R)
Good understanding and also simple way of teaching
Sabse simple jab 1st c atom par l.p.ho &free radical to+m effect &unsaturated g.p ho to -m
Salute Hai ❤️ 5 yr ago quality of education 🙏🙏🙏
If there is cl on the benzene ring then it will show +m bcoz of lp electron. But halogens are electronegative element then will it show -m ever???
The cpds containing lp in central atom shows +M effect but in case of Halogens ( F/Cl/Br ) the Inductive effect (-I) dominates over +M making it e- Withdrawing grp........Baaki saare cases me M dominates over I effect ......Hope you understood😊
@@丂卂工丫卂从 thanks
Best chemistry teacher in youtube 🙏🙏🙏👍👍👍👍
sir this sessions are amazing , and thanks for making a playlist to keep up with our track ,
NO ONE ON THE WHOLE TH-cam CAN TEACH ORGANIC AS YOU CAN .
i understand every single sentence bcz you break it down for us in so simple words and small videos
.
it would be my honour to meet you one day .
thanks for making my life a bit easier .
❤❤❤❤❤❤❤💖
It's my pleasure Sarthak 😊
@@atpstarkota sir please tell about lecture sequence.
i m doing randomly
its amazing sir itni aasnai se smjha diya aapne i m thankful to you💓
Sir but if O donate its lone pair then it will gain a positive charge with incomplete octet. Wont it make the compound unstable
U r just best explainer really … thanks for helping in clearing my doubt
Best chemistry teacher ever
No my vkr sir is best 👍 ek br unse chemistry pdhna
Sab samaj mai aagaya sir ....
Thank you...
Great job sir..👏🏻👍🏻 understanding concepts better.
Sir, in the 4th example which u have given why doesn't the π bond electrons shift towards the carbon that is directly connected to benzene ring bcoz both carbons have same EN VALUE as both are SP HYBRIDISED.
sir, what I know is, CH3 is an electron donating group,
so it should show +M effect…
Any Time Padhai Academy , CH3 is weak and activating group that shows+ M…
TIWARI BROTHERS
It will only show +I effect..
Made mesomeric effect so easy to understand
Thanx a lot sir... Now I learnt what is +m and - m... Only bcz of u...
Sir, are all lectures of goc sufficient for jee mains?
Sir, what exactly is Mesomeric effect? I mean, isn't it essentially same as Resonance effect?
From where should I strt Sir every point in this video is so important and useful....u have cleared my 100 doubts just within a few minute video
Thankyou sir for clearing such topics .. keep on making videos ..
Keep watching
This is very helpful me
Thank you so much sir
So nice of you, stay connected.
Sir NO2 me N prr jo + charge aata h... Usko NO2 ka O atom jis pr negative charge h... Wo bhi to pura krr skta h... Benzene ring se electron lene ki kya jrurat h...
King of chemistry.Thank you sir
In the last example why the electron flow is towards triple bond...
e flow is towards nitrogen by extracting 1 bond out of 3.
Best explanation and trick of mesomeric effect... 👍
U made ur concepts clear
Sir actually in my class my sir said that F shows +R and Cl, Br, I shows
-I when attched to the benzene ring..... And in this video you showed +M effect of Cl.... I am confused. Please clearify
bro....R M and I are different.....in ur case...the F on benzene ring must've been on the meta position....therefore it showed no mesomeric effect
sir you are the god of organic chemistry.
Awww ☺️ keep watching & shower your love & support by sharing with your friends as well for more such lectures .🤞
actually great teaching sir Very fluent and awesome teaching way keep it up
In the second last question (phenylacetylene) why is the conjugation that happens with ethynyl group dominant over the normal conjugation in benzene ring ?? i think the latter should be dominant since carbon isnt much of an electronegative atom .. like N or O atoms as in other examples. Please do correct me if i'm wrong. and yes.. YOU ROCK!
After 7 years this is still a true gem ❤
1) electron donation due to resonance is called +M effect
2)
sir aapki lessons bahut achi hai sir...aap meri bahut madath kar rahe hai....sir jab aap yeh bolte hai ki OH dominating resonance hai ....aapne woh kaise bola sir?
U r good teacher of India
Bhut acha samja rhe ho sir ji,,, thanks
Good presentation. But how to keep in memory so many case in one go ? Serialized ones would perhaps be better.
THANKS SIR U CLEARED MY DOUBTS...AND SUPERB TRICKS..
Sir these tyor of videos are so good🔥🔥
Thankyou vineet sir..
💘💘
Pls. Make a video of electrophilic substitution rxn , and compare among them , with all exceptions like NH4+. And how to see b/w. I and M effect
Thanks so much sir can u provide video on electron withdrawing and electron donating group????
Sir ye trick kya benzene ring se group attach ho tabhi valid hoga Varna sabhi cases mai valid hai?
Very helpful video.
Thanks a lot sir ❤
In Clorobenzene cl is electronegetive than benzene so it will withdraw e-, so it should be - M effect or not??? Please answer me......
Thanks sir . Please can you provide mcq s of this goc section through PDFs or videos.
Moral of the video:-if the compound which is directly attached to the benzene ring and contains lone pair,will show +M effect and vice versa
So can we say that +R corresponds to +M ? Or are there some exceptions?
same que thank u
sir in last question o-c is double bonded and o is more electonegative so o will not atrract electroon
ATP is very helpful in my Preparation.
Great 👍
Thank you sir for clearing my all doubt❤️
What will happen if both NO2 and NH2 are attached to benzene?
Thanks a lot sir
God bless you
So nice of you
Thank you sir, for helpful trick. please keep it up. 😊
In 2023 I am watching this video 📷🙏 nice lect
Sir u r superb sir apka bolna itna a66a or sikhna or vi a66a ,teacher hoto ap Jaise
good explanation sir. i am blessed to have this thank you sir......
First time this is not boring..!
Great, keep watching for more such lectures 😊
Thank you so much sir because of you Iam doing very very good in organic chemistry
Thnx for the extreme clarity sir......
Always welcome
After having a look ,my hand spontaneously goes towards the like button.thanks sir♥️♥️♥️♥️
Thaank you soo much sir very helpful...
Sir please make a video on stability of carbocation through resonance effect...
Very very thanks .... Really u solved my large problem
Sir pls tell why we haven't considered the repulsion of lone pair of O and pi bond in cooh as dominating.(at 5:07).
In that case it would be showing +M effect.
Since O is more electronegative than C, it will pull the pair of pie electrons towards itself despite the presence of lone pair.
Mesomeric effect is only for aromatic compounds ????
Sir aakhari wale mein kaise Kiya. Usme lone electronegativity toh dono mein same hai. Sir dominating conjugation kaise pata chalega.
6 yrs later..still these vids are enough to clear the entire goc concepts..literally everything is included..short vids..watch nicely..can compete the entire playlist in 3 hrs ..practice PYQ...more than enough..GOC ke que pakke nikal jayenge
thank you very much sir..never thought that i will understand this concept of mesomaric effect..this video really helped me a lot..😃😀🤩🤩
You are most welcome
It has already been asked, but would it be possible please to have a document for your videos please ? They are very helpful, but this is difficult to watch this every time I need a reminder of its content ...
+ m and - m are only for benzene ring
Thanks once again sir. It is my very luck to be able to learn things from you.
