Sir beginning glimpse shown that what a splendid lecture it is gonna to be. And i was in need of this topic. Thank you sir ji 🙏🙏 And plz come daily with such BOOM BOOM CONCEPTS 💥 💥 💥 💥 💥
Mka sir ring expansion or ring contractions pe aabhi tak ka boom boom lecture hai This is my one of the favorite lecture of all time . Bahut hi maja Aaa gaya Thank you so much for ur tremendous amount of help for us
Wow after watching this video I am confident on this topic thanks a lot sir u r awesome sakalaka bhoom bhoom pencil ki tarah 😀😊 From JEE aspirant 2021 ,Kolkata
Your channel is highly underrated and underviewed sir I am from Punjab and this video is way better than physics wallah or any other teacher. GBU sir!!
sir i see ur prevoius 2 video of carbocation but every time u come with some new concept ,challenging question that suprise me .sir aap to chemistry ki knowledge kai ocean hu i really thought that 👏👌👌😋😋😋😋
Sir next apka kaunsa VDO araha hai? sir organic reaction mechanism with stereochemistry bala questions mein Bohat confusion ho Raha hai. Sir plzz Uske upar ek VDO banayiye.
Sir mako lagta he ki ap mere concept clear ker dojeeaa (tollens and fa.....ling ) per video banadoje it come every year in jee advance sir mere problem ka solution app heeeeeeeeeeeeee ho sir ap hamari felling ko geante hooooo 😘
Koi v agr dekh rhe ho to plzz thoda sa idea dedo back bonding kaise pata krte h 😅mujhe malum he back bonding kya hota h prr khudsa crystal concept nhi he.. Maene dhundha v TH-cam prr acha mila nhi kahin prr. So, anyone plzzz btta do... Ya kal mae unacademy me live class me hi puch lunga sir se.
@@IITianexplains to sir phir hamare institute ke sir ne galat bataya hoga. Sorry sir. Sir vaise no2 se to stability decrease hogi to use kyu shift nahi kyya gya hai ??
Sir, ek बात मैं confusion raheta है।आप कहते है की शिफ्टिंग में hydride>phenyl>alkyl Dusare Kai teachers,vo bhi Cota me padhane vale ke video me hydride>alkyl>phenyl ये ऑर्डर बताते है।हम किसके ऊपर विश्वास करे?अलग अलग book में भी अलग अलग है। हम क्या करे?
Sir, मेरे quistion का जवाब आपने दिया था, मगर, carbocation के बगलवाले कार्बन के पास अगर ,2 methyl aur ek phenyl group agar hai aur agar ham methyl ko shift karade to बनने वाले carbocation के पास hyperconjugation, resonance aur tartiary carbon bhi हैं तो वो ज्यादा स्टेबल नही होगा? अगर carbon ke पास दो phenyl aur ek methyl group hai to किसका माइग्रेशन होगा? और क्यूं? प्लीज answer देना sir!!
Have you done reaction of 1,2,3-tri (hydroxymethyl) cyclopropane reaction with con H2SO4 to produce benzene at 460K ? Total 5 times rearrangement takes place in this case. Actually number of rearrangement is a thermodynamic based term and depending on enthalpy, entropy and Gibbs free energy change.
joy i have an answer whether u will understand it or not i don't know...... reaarange ment happens by shifting of electron to the empty p orbital as in the case of sp2 carbon in carbocation right ??? but in the case of carbanion already filled p orbital is present ..(sp3) that's why there will be repulsion .....and no rearrengement ...i think that would the reason ...
@@joypalit6408 are h+ thodina shift hota hai ...electron ya bond hote na shift ...to uski jagah + ve charge lagate hai ...aur free radi cals can easily undergo dimerisation which give them more stability
Jab tak IIT JEE rahega carbocation ka naam rahega😆😆
Mazza aa gaya sir. From zero to mentos level, you rock and this is your beauty. Love you sir ❤😘.
You won't believe I have been searching this topic for past few weeks. Finally you uploaded. Thank you 😭😭😭
che'M KA' best teacher.....we r blessed to hav u
Boom booom concept sirr🔥🔥🔥🔥
Finally I found a good video on TH-cam. Thanks to iitian explains team
Aa gyi video😍😍😍. 4 days without ur video is like chemistry without organic. Dhanyavaad guruji
Dimag ka kima ban gaya... Sir aap great ho.. no adjectives available.. iss video ko achese samajh ne ke liye 3 bar to dekhna parega .. kam se kam..
Machayenge mka sir ke sath.Bohut khushi Ho rahi hai apse padhne mein plus par bhi aur yt mein bhi.Khob bhalo sir!!
Guruji aapke content aur aawaaj se kabhi bor nhi hota hu
I am now habitual to it...
Sir beginning glimpse shown that what a splendid lecture it is gonna to be. And i was in need of this topic. Thank you sir ji 🙏🙏
And plz come daily with such BOOM BOOM CONCEPTS 💥 💥 💥 💥 💥
MKA sir rocks.🤘🤘🤘😎😎.
Super Concepts.
Mka sir ring expansion or ring contractions pe aabhi tak ka boom boom lecture hai
This is my one of the favorite lecture of all time .
Bahut hi maja Aaa gaya
Thank you so much for ur tremendous amount of help for us
Maza aa gya guruji... Level chadhne pr ek baar thoda difficulty hua tha but clear ho gya last mein.... ❤
Thank you sir .apka VDO Bohat jyada Kam araha hai.YOU are the best.🏆🏆🏆🏆🏆
Sir u have rekindled my hopes in organic chemistry..iitian explains has a perfect record in removing my conceptual doubts😍
Sir first view..First like...Big fan of yours...Really admire you way of teaching...
Im first

Awesome explanation sir! This channel is highly underrated...
Sir gajab u r the best keep up the good work proud to have u 👍👍👍all my concepts were cleared
Sir, u r really interesting person......make feel us comfortable with every topic
Whenever my concepts my shatters I rush to Guruji videos without waste of a minute
Sir please make a playlist where chapterwise topics included.
Bhot hi maza ATI h jb ap padhhate h
Sir ur the best educator I have ever seen❤️

Sir plzz free courses lao unacademy par bahut help hogi
thanku dear sir
Sir favorski rearrangement me bhi ring contraction hota hai
Par kyu??
Koi v agr dekh rhe ho to plzz thoda sa idea dedo back bonding kaise pata krte h 😅mujhe malum he back bonding kya hota h prr khudsa crystal concept nhi he.. Maene dhundha v TH-cam prr acha mila nhi kahin prr. So, anyone plzzz btta do...

In demyanov rearrangement of cyclopropyl methyl amine , cyclobutyl cation forms from cyclopropyl methyl cation(dancing resonance) .... Why😳
Can someone put subtitles. I can see that is a great quality material, but i cant understand a word of what he's saying.
at 13:50 you have told wrong. pls correct it no2 will migrate
Nope

What about Baldwin Rule...563748..
1:2shift occurs only once in a reaction
Have you done reaction of 1,2,3-tri (hydroxymethyl) cyclopropane reaction with con H2SO4 to produce benzene at 460K ?
Total 5 times rearrangement takes place in this case.
Actually number of rearrangement is a thermodynamic based term and depending on enthalpy, entropy and Gibbs free energy change.

Why rearrangement does not take place in carbanion or free radical

@@shubhamjoshi9748 in case of carbanion h+, ch3+, ph+ will shift and in case of free radical h., ch3. ph. will shift. But that does not occur.
@@joypalit6408 are h+ thodina shift hota hai ...electron ya bond hote na shift ...to uski jagah + ve charge lagate hai ...aur free radi cals can easily undergo dimerisation which give them more stability
@@shubhamjoshi9748 proton transfer or alkyl/phenyl transfer
@@joypalit6408 that's a different thing i guesss...proton transfer is not related to rearrangement
