Bhaiya wo schedule dene ke liye bohot bada thanks...ek roadmap tayyar karna tha bas uske liye bohot important tha wo...thank you so much...and content pe to koi sawal hi nai tha kabhi... Organic samajh aa rahi hai ab
Itna tagda aur best kisi ne bhi nahi padhaya hoga , bet ❤ 😊
Other Teachers- Lets do PYQs (2024,2023 JEE Mains PYQ)
Sachin Bhaiya - Chaliye Confidence barate hai apka (JEE Adv PYQ , INCHO PYQ)
Bhaiya pls like kardo.....
49:00 what about the beta hydrogen present on the ch3 group present on the same carbon atom as Cl
homework answer advance 5 3 unique 2 showing GI
2+2+1=5
Bhaiya ye chapter mere coaching me karwaya gya.. Kuch samgh nhi aya... But apne ke video se module ke question bahut easily ban gye..... Thank you so much❤❤❤ .. I even thanked my classmates for suggesting u videos.. .... Thanks a lot
Quality content from a Quality person ❤❤❤❤❤🎉
Hlo bhaiya may u read this msg
Bhaiya bi blindly follow u for organic chemistry and u are the best teacher on u tube super best... Bhaiya
Bhaiya ky aap physics v pdhao ge?
Quality content 🔊
was eagerly waiting for the lec... Thank You :))
guys 6k views hai and about 357 likes , bhaiya ne straight 2hr lagatar padhaya hai ...... he deserves appreciation from our end ........and bhaiya hats off for your efforts ...........I'm one of your old student from unacademy plus and guys sach bol raha content delivery mein koi bhi difference nhi hai ...........sab kuch almost same and for free ..........make sure to hit that like button
48:03 bhai tell me how 2 product is possible left wale main gi possible nahi hai kya ?
@@JUSTANSHKUMAR Mere bhai yaad kr ki for GI on a double bond inside the ring ki condition hoti hai ki bare minimum 8 members hone chaiye ring mein becuz if size of ring will be small then trans isomer will not exist due to high angle strain .......In the given question we have double bond in 6 member ring hence trans isomer will not exist hence GI will not be observed......Hope so it answers your question
Padh bhai padh ......have a hardworking day mate 🗿
@@shouryamkumarsinha4798 thank you mate btw revise kaise karte ho short notes or long notes
and All the Besttttt
@@JUSTANSHKUMAR bhai mera scene thoda ajeeb hai ......... like physics short notes and for some chapters in chemistry i'm using short notes while in some i prefer long notes{actually ready nhi hai short notes} , maths mein I prefer to go through pyq and question which I did wrong in past . Aree all the best to you too brother ........keep hustling , meet you at IIT someday😉😉
48:03 in O enantiomers are formed but in Q that is locked chiral centre.
How??
Can anyone tell me please
Bhaiya at 50:06 You have told the reason that e2 elimination will be more favorable in the second compound due to more availability of hydrogen ( a better probability to attack ) but we check the e2 elimination by acidic hydrogen even in M.S .Chouhan ( Exercis of Alkyl Halides ( Elimination ) in level 2 Comprehension 1 Ques B option S it's the same question but the answer is in the favour of first compound .
And in the first compound it is resonance stabilized compound .
Good to see you sir :)
1:36:26 answer is 5
Thankyou bhaiya ❤❤❤
Steal deal :

Sir iss Wale main hojaega... 😅
(But haa last lecture main jo aap bol rhe the ki notes ratt ke nhi aate yeh aapje aaj 100% prove krdia) 😅
Thanks Dada ...khup.Changla lecture aata parantr Yt varcha
day 2 of oc
5 products bnege of adv 2011 ques
3 products and 2 of them show gi so 2 more products
I don't understand a letter my coaching organic sir teaches us. Thankfully I stumbled across your channel and have been following thoroughly ever since. JEE 2025
Sir i have doubt that z16 question me 1st reaction me saytzeff product banna chiye na phir na 2nd reaction hoga
Thank you bhaiya❤
Thank you bhaiya ❤. Answer to Z15 is 5.
same
Love you bhaiya
Thanks for the great content❤❤
Whenever I start writing, HE SAYS "LIKHO MAT". I just wonder how he knows that :__)
@1:07:46 Bhaiya here in (U) you have drawn trans product in Hoffmann Elimination but the cis product will be the least stable product naa? Bhaiya please clear this doubt.
BTW best lectures I have witnessed till date👍
Bhaiya please reply
@@krishnaverma6261ha bhai shi ho tum, sir ne product ke jgh concept btane pe Dhyan diya h.
I think jo sir least stable bol rahe the, wo among structural isomers tha. Cis trans are configurational isomers
bhai i think you made z1 to be saytzeff product whereas you said it as hoffmann..
ans to z15 --- 5 alkenes
I wish I could like your videos a million times.
Thanku bhaiya ❤❤❤
1:29:12 good question
1:37:11 in that question, after reacting with alc KOH won't it form the most stable alkene which would be 1 bromobut-2-ene... And then how the next reaction is possible? Kindly explain. Thanks
NaNH2 is a strong base, hence it can form an akene which is even more stable
The Br shows mesomeric effect to double bond so it is stable rather than 1 bromo 2 butene
Thanks to god of OC
Sachin bhaiya ❤️❤️
H.W Z15 Total 5 product ..... 3 distinct product jisme se 2 ke GI bhi hai
sir in z24 why is conjugation not preferred u had stated that if there is conjugation then there is no hoffmann or saytzeff product but only the stable structure but then u contradicted yourself over there
hey wont elimination occur from the carbon in wedge attached to carbon containing cl in question 'S'??
You are right. It should cause 3 cases of removal of H are possible bhaiya took only 2
Sir I have a doubt in z24 you said that the least stable possible is formed [hoffmann] over resonance but in z21 you have considered resonance over least stable product. you said in concept that if resonance is possible we don't have to see any hoffmann or saytzeff. can you please tell me if I have missed any other concept there?
I am a dropper ,I am following your OC playlist sir it's wonderful and I am doing your homework and MSC.
48:03 can anyone tell me how 2 product is possible left wale main gi possible nahi hai kya ?
I also have the same doubt brother 😢😢
Go and revise Isomerism 🙂
Sir last que mai D: propene hona chahiye na??
46:05 sir yaha cis trans nhi hoga
1:49:11 hoffmann elimination would take place
aren't 1:49:53 and 1:58:38 contradictory...pls help me with this doubt
THANKS BHAIYA ❤
ANSWER to the hw question is 5(3 distinct + 2GI)
bhaiya plz arrange the videos in a queue
Already playlist hai dekho
How gi is possible in o question 46:05sec
Thank you so much sir
bhiya aapne z24 mai toh hoffmain hi banaya jab ki conjugation presnt tha but aapne z21 main saytzeff bana diya conjugatio ke wajah se ....toh inme se ek toh glt hai iska mtlb ....plzz correct me if am wrong
YEAH I HAVE THE SAME DOUBT.. PLEASE MIND TO EXPLAIN IF YOUR DOUBT WAS CLARIFIED
bhaiya if you dont mind 1 example ap boards exam ke liye bhi dediya karo ki boards me isme kis tarah ke sawal ayenge ya aa skte hai
Sir aap saare Named reaction bhi karayenge na jo jee me puchte hai?
I could not understand the planner you shared at tg. Pls tell till which chapter would you finish till 15 dec
Carbonyl comp aldehyde ketone
So amines left. right?
you are the because
Sir Question P me sp2 hyrbidised hai C
Sir do you prepare all these questions on your own??
thanks you❤
and also in z23 wont the final product
be conjugated
answer is 5 sir
Answer is 3 of HW questions
Done
49:05 in the S question the reaction can proceed through the wedge CH3 which is with Cl, right?
Hey sir
Structural Isomerism was not in schedule what to do of thatt?????

1:38:07 answer given is different
Lecture is amazing sir but respectfully saying that from past few lectures many confusions are arising because you sometime contradict your saying and as this is not a live class so there is no possibility we can clear our doubts. for eg in this lecture also in qs z-24 you contradicted your saying that if resonance is possible then we dont have to see any hoffman or saytzeff and sir if i took the concept wrong then i am really sorry and i request you to elaborate more on such type of questions and concepts.
@VN-bo6cd
Hey, have you found any relevant reason for that question, I too was confused in this question and I completely agree with your point , I also had similar confusion in one of the past lecture where SN2 was discussed and its rate was directly proportional to e- deficiency and inversely proportional to crowding , sir told us to give importance to crowding but then contradicted himself in the same lecture afterwards by giving importance to e- deficiency in some questions
@@Chandra_Mohan_Singh. importance is given to e deficiency not crowding
yes i also have the same doubt i am very confused with that..............
answer 5
Sir of you have PDFs of all lectures, please share them sir , ik should make own notes making notes sir but I didn't made all examples sir, so I request you to please share them if available sir
