Yes sir, in JEE Advanced 2015 paper 2,there was Paul Knorr synthesis of Pyrolle type, and here we learn paul knorr synthesis of furane. Such a good content👍
Sir I'm really blown by the level of your understanding. I really wish to have a strong understanding as yours. You are amazing sir. Keep the great work sir. Will always support you till the end . Huge respect sir 🙏🙏🌷🌷
Sir, we can avoid contraversy in last, when we go by long aldol method only. Rearrange carbocation and we can get option D straight away. And super moment in this question is sacrifice of furan type compound,which is aromatised to a condensed ring. Thanks for putting such stuff on TH-cam platform
@@IITianexplains sir woh dialogue sunne ka mann ho raha hai.....agli video mein daalne ki koshish kijiye na sir....agar aap ne alredy ban rakha hai toh koi baat nahi hai sir.....love you so much sir.....thank you very much
Sir after formation of A won't the second compound added undergo retro aldol followed by pall knorr to give a similar methyl furan? Though none of the options give that wouldn't that be a major product of this sequence? Lots of love :)))
ultra strong concepts of goc at each step....those who are solving make sure you check each possibility for the stability of the substrate BEAUTIFUL QUESTION SIR!!!!
The question was good but the second part makes no sense, it's like deliberately attacking the reagents( I know I'm not an expert that's why I don't really understand in depth but still it makes no sense)
Sir why it is necessary to remove the -H from beta position as if H+ will attack the the pie-bond will break and partial +charge appears on carbon then lone pair on other carbonyl will attack on it and the ring will form then the the H will removed and pie bond will be formed Please correct me if I am wrong plz sir Thanku sir

Till compound A: Everything is fine
Till compound B: YEH KAHAN AA GAYE HUM SANAM LIKHTE LIKHTE....😀😀
Hehe 🤓
Sir this just beyond advanced level
Comment Master This problem was difficult. The last part especially where you get the heterocyclic compound and you do the attack of H2O.
NO, this one is under Advanced level. The reagents are asked in Jee Advanced.
100 times above advanced level
Advance level ke upar hai...

Good luck
Sir increase frequency at this peak time please
beautiful question sir ... extreme level me maza aagya sir .. awesome explanation
Sir u looked smarter with the beards
Awesome question🤩🤩
Super awesome explanation Guruji 😍😍
Completely different on plus you are!!
Sir I 💟 your teaching!!
Khatarnaak
Sir apki vedio dekhte time movie jaise mehsus hota h ekdm suspense bna rhta h end tk🙏
Best question till now in this series!!!
Thanks a lot sir !!
Sir 1st set mai. 2nd reaction(H+ /warm) mai aldol condensation kyu nahi hua?
Last step was fantastic guruji

bhot acha ques lye ho sir aap.. ye series bhe ache hai
Very nice qu sir thanks for session.
sir aap phir se aapka signature dialogue bhool gaye....
Acha 😁

Sir u are great
Brilliant
Sir first step mei carbon se kyu ni krwaya attack...it is more nucleophilic??ring bhi 5 member bnti
Sir i am facing a doubt..if that furan-ic structure loses its aromaticity... how can just resonance energy in the final pdt account for it...
Great 👍
guruji jyada hi advance hogya😁😜 thank you for this video,and your efforts; we will crack chemistry in advance 🙏😎🔥
Macha diya sir......Tussi great ho!!!!!
Guruji isme to aap ke ball hai
But aap handsome dono look me lagte ho
Amazing video i am eagerly waiting this video

Mast
Bahut hard hai sir🥺🥺
It's too much complicated and so learning question..💓💓
Superb sir
Guruji
Oopoppoop question
Mja aagya .
ultra strong concepts of goc at each step....those who are solving make sure you check each possibility for the stability of the substrate
BEAUTIFUL QUESTION SIR!!!!
Sir ismei Second step mei acid catalysed aldol kyon nhi hua?
Full concept cleared
4 ghanta badh uthna padhega...lekin koi dikkat nahi, Guruji😎😎😎
Sir , mazza hi aa gya
Toppppp lewel concept
Heart touching ❤️❤️❤️❤️❤️❤️❤️❤️❤️thaanku sir
Omg I'm sure that you have different ideas for this
The question was good but the second part makes no sense, it's like deliberately attacking the reagents( I know I'm not an expert that's why I don't really understand in depth but still it makes no sense)
I was desperately waiting for this video since three days.. nice Q
Sir really grateful for your efforts 👍🙏🙏 🙏.Thanku Soo much sir.
I got d answer sirji all thanks to you. Love you efforts sirji 🔥🔥
Waiting!!
sir you could have increased the video length and

Thanku sir
Please ask a clear question.
Chhota packet badaa dhamaka
It's gonna be awesome lescure😁😂😁😭🙄😉👍🙏😭😭😭😎😎😭
Love you sir ji 💜💚💙 no one stands near you in terms of teaching.......
Sir humne A banate hue 2nd step mai that is H+/ warm usme acidic aldol kyu nhi kiya just like we have done in A to B????? Plssss
Same my doubt
Aldol requires alkaline media
No Sanskar aldol can be done in acidic medium as well watch what sir has done in A to B hear him properly
Pls upload vdo of physical
Great question.....kaafi kuch revise ho gya!!👌👌👍👍
Sir cap kahan gayi apki
Sir last step aj tak jitte question kiye unpe shak paida kar rahi hai Sir please help us to digest the last step .By the way sir question was SAVAGE
was a very good ques!! difficult and intersecting
Sometimes,I have to accept that life is not so fair
Aise kaise sir.. itna rearrangement ek step me kaise!? Aur sir acidic medium me aldol kiu hoga sir... Pls reply
SIR IS JUST AWESOME!!!🔥🔥🔥🔥🔥
Sir you attitude with this beard and dense hair, is like a lion ....
Full of Power and enthusiast 🦁
Awesome question .you are great sir.
Bahut hi sundar question tha guru ji ❤️❤️
Thanku very much sir for these lectures thanku very much sir❣️❣️❣️🙏🏻🙏🏻🥺
sir (NH4)2CO3 ka bhi use krein kisi reaction me sir plzz
❤❤❤❤❤❤
GURUJI, apka qualitative analysis wala video kafi hai kya adv ke liye..
Great concept with real visualisation ♥️
Thank you Guruji 🙏
Thanku vary very much sir
Super teacher
Completed your 2020 series today.. But started today only.. 😅😅
Good
pranaam sir ji i think sirf ap hi advanced level ki chize padhate ho
Guruji aap mahan ho
charansparsh guruji Aashirwaad banaye rakhna
Sir doubt plz explain how that tautomerisation took place in ending and formed two ring structure sir plz explain in next video
Sometimes By seeing option only we can write mechanism
6:05 sir oxygen ka positive charge kaise khatam ho gaya
Sir kya pahle step me hi aldol nhi ho sakta usme bhi to h+warm hai
sir pl help with Retro Aldol
Bhai in the matrix they had given the product
Last me Aldol kyu ho gya??
Awesome 💯💯
In which books such questions are there??
This question is just awesome sirr 🙏🙏🙏
Sir here KMnO4 is used as oxidizing agent not as oxidative cleavage.Why?
Sir, please resolve this confusion in next video.
Alk kmno4 heat u will get cleavage,dil kmno4 u will get vicinal diols
Hi venkata
But where alk or dil is mentioned here.
@@AKASHSINGH-cu1hh heat should also be there for cleavage
kmno4 aromatic ko break nhi krega
But 🔼heat also mentioned there.
A tak toh aya a ke bad duniya idhar ki udhar hogayi
@ 2:55 why not acid-catalyzed intramolecular aldol guruji ???? plz reply
Same doubt
extra ordinary Q , Guruji
Sir will Kmno4 not break the double bond as well.
There’s only one equivalent, also the compound is aromatic it would be like oxidising benzene
No bro cause cmpd is highly stable and also it's one eq
Nahi yaar woh aromatic hai toh benzylic hydrogen ko oxidise karne ki jyada tendency rakhega
Kya Question tha😀😀😀
Sir ek doubt he A reaction me diels alder reaction hosakhta tha na?
No Devansh.
Yaha bhi present sir,from andheri duniya🤣🥰
Sir how can we contact you
Sir frequency badhaiye...
Sir kya aapane jee chemistry theory pada rakhi hai kya ??????
