Sir , I just want to tell you what a difference u r making in our lives. Thank you so much Sir, for your hard work and efforts. This really helps. A senior whom you have taught in coaching some years ago, she recommended me to watch your videos. I feel very grateful for your hard work. :)
Sir mujhe tho lgta h ke agar apne chemistry m organic na pdai hoti ..toh shyad puri life m itne ache organic muje kbhi ne ate ... Thanku so much sir.. GOD always bless you.😍
Sir if I get a good college, I will come to meet you personally, u mean a lot to me. I don’t care how, but I will surely come and meet u. To thank you.😊
Sir at 10:10, '-OCH3' group shows '-I effect'. It also shows +M- effect but it is when there is resonance in the chain. Here there is no resonance. So, electron density must decrease..... Then why did you point that the electron density will increase. Sir please reply.
I am really flattered of ur teaching sir...u r not a teacher u r heart beat of millions of students...and I really enjoyed the whole series...at last only one thing I could say thank you so much sir for ur dedication and determination...🙏🙏
Sir depression dur karne ke liye aapke lecture ka notification hi kafi hota he or lecture ke baad to depression kya hota he bhul hi jate he lagta he kisi family member ka support mil gaya ho 😢😊☺️ I want to giveThanks to world's best teacher and motivator💓
Bhai pata he bhi depression kya hota he !!! Bakbas baatein mat Kia kar without actually diagnosed by it !!! I was diagnosed by depression after the death of my best friend and brother in a car accident !!! Not like your fake depression of getting left by a girl whom u were thinking to marry !! So just shut up and don't spell that word it's not a joke
@@Pepe-jw7xw i feel you bro... Aap jese logo ko dekh kar hi lagta h ki apni life thik chal rahi h koi struggle nahi h.... I feel depressed at times... But then I think of guys like you who lost family members... Sad😢😢
@@rchoudhary7944 OCH3 as far as I know doesn't give +I effect. O is an Electronegative atom. I think sir didn't notice those groups properly Edit: Maybe sir tried to explain it by bringing Oxygen's electrons into resonance . But still a negative charge on Electronegative atom makes the specie unstable
I am extremely sorry sir for doing this, I was searching something on TH-cam and extremely due to touch screen phone your hydrocarbons series got reported , 😢😢 I am so sorry for this sir. I am a regular student of yours and I truly trust you everything you say 😣😓
Great video sir! Just one question that I need to ask is that during addition of water, we're saying that 2 degree carbon has a more stable partial positive charge on it but, shouldn't the magnitude of that positive charge be reduced due to increasing electron density because of +I by methyl group? And if that's so then primary carbocation should attract a nucleophile more.
Alakh sir ki wajah se student aaj kal coaching classes ya school mai physics chemistry ki proper padaai nhi kar rhe kuki unhe pta h humaara physics wallah zindabad h

Sir , I just want to tell you what a difference u r making in our lives. Thank you so much Sir, for your hard work and efforts. This really helps. A senior whom you have taught in coaching some years ago, she recommended me to watch your videos. I feel very grateful for your hard work. :)
This video shows that 200,000 students were regular in watching hydrocarbons chapter's series.
Sir mujhe tho lgta h ke agar apne chemistry m organic na pdai hoti ..toh shyad puri life m itne ache organic muje kbhi ne ate ... Thanku so much sir.. GOD always bless you.😍
Thanx for your efforts sir g
Sir, in the playlist hydrocarbons lecture no. 6 is not there. I would recommend others to search it up separately 😊
Tution teacher ki zarurat nahi ha!!! Jab hamara sir hai🙏🏻🙏🏻
sir class 12 organic p bnaeye Na bdw sir lots of love from bihar
Hey ansaar my question
Sir, I request you to make a video on books as you promised.
Ty sir.. Ty so much... Now have no doubt about addition of water...
Great speed sir 👍👍
Sir aap apne hisab se padhae....apko jaisa pasand hai vaisa...Thank you sir for such a wonderful platform......All the best..for future
Thanks a lot sir..stay blessed alwz sir...

You have changed me sir.
Etna concept mere pass nhi hota agr app nhi hote.

Thanks sir !!! Finally finished

Then why did you point that the electron density will increase.
Sir please reply.
Och3 is also a group which has m 3ff3ct and mesomeric effect always has a high preference as compared to resonance and hyperconjugation.
@@anurimamisra431 IT IS SEEN WHEN IT IS IN RESO. HERE IT IS NOT IN RESO.
Sahi pakde hai ....
@@doctorsjourney352 Yes
U anand it's alkene and it has resonance.
At 9:55 we can't use +M because there is no resonance, -I effect will be considered
Like if you agree👍
And Rate proportional to stability of alkene
Bhai inductive hi toh hai
Also , free radical have been proposed as intermediate in the demercuration step(although details of demercuration reactions are still sketchy).
Sir organic chapter wise kab sa aayage 12 ke sir bhoot time beet gya thoda jaldi sir bhoot pending padha hai...🙏🙏
Tbh I'm skipping my online classes from 2 months just to watch your lectures sir. You have helped me a lot in this lockdown. Thanks a bunch😊🙏❤

Sir 10.44 mein omdm ka rate wale q mein OCH3 +M kaise dikhayega vhn toh resonance h hee nhi.Yhn toh uska -I lgega tb order is b>c>a
Yes bro u are absolutely correct!!! 👍🏻👍🏻
I was also having the same opinion!
No bro OR groups jo hote uska +M > -I hota h issliye woh wha +M ko trah kam kar rha h
Och3 gives +m effect
Kon kon sir se apni zindagi me milna chahta h like if u effort👇👇

Kesa gya paper
Khtm h bhai😂
9:45 system conjugated hi nahi hai kahan se donate krdega electron OCH3 +M se..Ulta -I effect se kheenchega electrons
Hmm;
Yahi to maine bhi comment Kiya hai
+I se
Right
