Sir jo aapne 44:52 pe O wala eg liya usme agar O -I show krega toh +M bhi toh krega that means overall it will act as E.D.G so it will decrease the stability of transition state thereby decreasing the rate of sn2 rxn as well

at 39:09 sec sir told that o=c-cH3 is ewg so transition state is more stable but how can it possible agar kisi ne + ve charge se election kechlega tho vo unstable na kaise stable hoga agar apko pata hai tho please mereko bhi patado na please
1:05:00 ... I used method of elimination here... The product will be inversion product.. So i eliminated 2 options now I got to the point that fluorine will not leave.. So there was only one option left... C... This is a God method. 😎😎😎
i really wish he could be my mentor... Eve though my curret teachers are really good, our class is spoilt by the over enthusiastic guys who have already studied a lot beforehand and are just better... They increase the class pace like anything... In real world, the RDS is not always the slowest XD!!!
57:43 in SN1 reaction , wont there be rearrangement of carbication and then OCH3- grp will get attatched to 2 degree carbon intead of 1 degree from both front and rear end ? Also i didnt understand how did the double bond vanish in the same question . It would be appreciated if someone could clear this doubt
First of all notice that the double bond got missing in the product of sn1. Second don't confuse resonance with rearrangement . Third, there can't be rearrangement as hydride shift would cause the plus charge to come on sp2 carbon which is more unstable than 1 degree carbocation. Fourth , notice that when carbocation is formed by removal of br- ion, then even if resonance happens we get the same product so anyways the product is same (but mind the double bond). But here you will also see that the stability of carbocation has increased.
U r truely a GOC ( GOD OF CONCEPTS )...LITERALLY NO ONE WOULD HAVE EVER EXPLAINED SUCH A DEVASTATING TOPICS WITH THIS MUCH EASE !!!! 🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻

Sir aapka lecture dekhar dil garden garden ho jata hai😁😁
Bas wahi tak rakhna
😅😅
55:35 *Just a heads up,there will be OH in place of CN for SN1 in Q3), OH will be the nucleophile*
Yea dude
Sir you are actuall one in 'A LAKH'...😍
38:28 EWG to C se attached h jis par already partial positive charge h to vo to unstable karega na Carbon ko???🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄
Bro he is tell that , that carbocation itself is a better ewg
Whole COCH3 is a EWG not only O=
Yes bro same doubt
actually sir ne transition state ki baat kari hai, toh transition state mei toh 2 nucleophile ek sath attached hote hai (ek leaving group and ek attacking group) jiske wajah se agar electron withdrawing group rhega toh wo dono nucleophile ko stabilise kar paega.... watch 34:03
I am a arjuna jee aspirat but still studying from alakh sir
Even I subscribed the batch but i understand more here
I think this video is Nobel PRIZE winning for alakh sir
In 52:00 In the products there should be OH instead of CN ?? as it is given in the presence of water ?
Yesss!!!!👍🏻👍🏻
🙏🏻🙏🏻 JITNA THANKS BOLU KM H SIR APKE LIYE
sir u explain very well...i m really thankful to u coz i was facing problem in SN1 and SN2 but after this video...every problem is cleared...love and respect from himachal pradesh
Hey ..
Kya aph entrance clear kya?.
44:25 , Structure 1, (ring with oxygen) has the 1° carbocation not 2°.(although backbonding exists)
And second one has 2°
Nice observation brother
Hats off to your hard work. You are just great. Words will fall short to express my gratitude towards you ❤️❤️❤️. Thank you so much for being such a blessing for many neet and mains student.
Hey this is good i did this today too
I mean Maine bhi aaj sn2 reaction pda
@@sachinbhardwaj6668 good
Everyone is talking about super 30 but you are the teacher of Super crore sir.... We love you sir❤ thanks for helping us... Thank you for helping those thousand students who can't afford coaching institute...(For Alakh Sir and RK sir) we are from family physics wallah
Sir,39:05 pe jab ch3-co ek -I group hai to...vo to electrons le lega na ch2 se jispe +ve charge hai to unstable ho jayega?
Plus I hoga shayad sir se mistake hogai
EWG C se electron lega to use electron ki kami hogi jo vo X ke electron khichkar puri karega
@prachi munshi... Even I got the same doubt!!!!!!!
@@omkargaikwad7130 Sir ne likha tha ki jitna stable TS, utna fast SN2.... Main poori tarah confuse ho chuka hoon😁

1.00.00 sir aap genius ho exactly yahi q tha mere mind mai sir salute hai aapko
Kya samjhaya hai sir maza aa gaya 🤩🤩🤩🤩
It was a great lecture ❤
Sir you are better than everyone..every teacher and every teaching academy
at 39:09 sec sir told that o=c-cH3 is ewg so transition state is more stable but how can it possible agar kisi ne + ve charge se election kechlega tho vo unstable na kaise stable hoga agar apko pata hai tho please mereko bhi patado na please
Best Concepts of Reaction Mechanism. Easily Understood due to U Sir. Thanks for this big course. Salute to you sir.
1:05:00 ... I used method of elimination here... The product will be inversion product.. So i eliminated 2 options now I got to the point that fluorine will not leave.. So there was only one option left... C... This is a God method. 😎😎😎
i really wish he could be my mentor... Eve though my curret teachers are really good, our class is spoilt by the over enthusiastic guys who have already studied a lot beforehand and are just better... They increase the class pace like anything... In real world, the RDS is not always the slowest XD!!!
That's the closest thing to reality that I have ever seen regarding schooling
@@awakenonline5098 yep!!
@@drbullah1388 are u in class 11
😂😂Hell yeah!!
That's so true.. RDS is not always the slowest step! Loved it!
Best lecture on Sn2 I have ever seen
Crystal clear 💯✊ 😇
Aapke peer padhane ka maan kr rha hr u r great sir god of chem ❤️🔥😭
Hats off to ur Hardwork
Are you from kashmir?
You are best teacher of organic chemistry
Sir 53:00 me chiral carbon nahi hai isliye racemic mixture and inversion,retention nahi hoga
u r right
Exactly bro
Love u sir aapne saare concepts clr krdeye vo bhi us chemistry ke part se jisse mujhe sbse jada daar lgta tha
57:43 in SN1 reaction , wont there be rearrangement of carbication and then OCH3- grp will get attatched to 2 degree carbon intead of 1 degree from both front and rear end ? Also i didnt understand how did the double bond vanish in the same question . It would be appreciated if someone could clear this doubt
No bcoz allyl carbon is more stable than 2 degree carbon that's why no shifting take place
First of all notice that the double bond got missing in the product of sn1.
Second don't confuse resonance with rearrangement .
Third, there can't be rearrangement as hydride shift would cause the plus charge to come on sp2 carbon which is more unstable than 1 degree carbocation.
Fourth , notice that when carbocation is formed by removal of br- ion, then even if resonance happens we get the same product so anyways the product is same (but mind the double bond). But here you will also see that the stability of carbocation has increased.
@@urtatota1621 SN1 ka double bond gayab kaise ho gya
Sir aap jaan hai hum jaise students ke
Love u so much sir.
Outstanding explanation gurudev🙏🙏🙏🙏

Sir 11th orgainc k continuation me hi 12 ki bhi organic karwa dijiye .. baki sab samajh aajata hai ..par organic ke liye apki guidance chahiye..
And Thankyou so much sir..you've been doing a great job in the history of educational videos. Thankyou sir. No matter when you complete the syllabus, we'll always be lucky to have a teacher like you. 🙏 I've studied in aakash and atleast in my case..they just ruined my physics and chemistry. You came as a light of hope. Thankyou sir. 😊🙏❤✌
u r cute
Same sis ... I m a member of akash and still do my study with sir... 😃
Sir u r amazing.....ajtk kbi sn reaction smj ni aaye aj peli bar lga h ki han kch bahot smj aagya😊.....keep rocking
Physics wallah ♥️
Sir is video ke end question (1:08:52) me SN1 me leaving group se order to correct h lekin. SN2 me apne bataya tha ki jitna acchha EWG hoga wo jyada SN2 dega stability of transition state due to (-I) effect order-(d>c>b>a). Sir please reply
The key to all concepts lies in your hand sir g
And you guide us to the correct path LOve from Dewas (MP)
sir i was not able to understand sn1 sn2 rxns these two videos of sn1 sn2 made it all clear thanku sir☺☺☺☺
Hit a like for alakh sir hardwork
Sir cant explain my gratitude to you. I am very thank full.
And you have a smile that can light up the whole room .
Salute you sir 😊👌👍👍👍💕💓💕💕👍🤲🤲💗👍🤲🤲🙏😆😆❤️🤩🤗 sir maan gye aapko .....sir AAP physics aur chemistry dono itna crystal clear concept ke saath kaise padha lete ho .....woowww really amazing sir ..main Allen me 11th 12th dono padhi hun .koi teacher itna crystal clear concept nhi kiye hai ....💐💐🌷🌷🌷🌷🌺🌺🌹🌹👌👌❤️❤️❤️❤️❤️❤️
Very supportive for organic chemistry💓💓💓💓💓💓
Thank you sir for changing my life with your 66 videos of organic chemistry🔥🔥💪
Soul is on 🔥🔥🔥.......laajawaaab sir jiiii
Sir we can compare the ster.. hindrance with inductive effect 👍👍👍
No it's different phenomenon
At 54:00 there should be only one product since there is no choral carbon because c is surrounded by 3 methyls
