9:51 but mam resonance effects dominates over hyperconjugation and inductive effect, then how the migration of aryl group take place, i think the carbocation will form where phenyle group is present 8:53
Mam I was a maths student in BSc and now Iam pursuing MSc with Chemistry...My Inorganic and Physical Chemistry part is good bt Organic chemistry is weak....pls suggest some book or study material to understand the basics...🙏
Mam kindly facilitate us with ur video lecture about lossen, Schmidt and hoffman rearrangements . If u already have done kindly facilitate me with that video link.
In between eg 1 and 2 there is an example in ph grp is migrating, and the resulting carbocation formed will be less stable because of EWD (COOet); may be iam wrong can u please check once
Mam in 1st question . When hydrogen will move to the carbocation so it would have +ve charge , it can't take its electron pair with itself because it is less negative than carbon atom
Mam jo last vala example hai ma agar h plus ke presence ma hi ch2+ benzylic carbocation nahi bana sakte kynki 3 carbocation se benzylic carbocation jaydea stable hota hai apne starting ke video ma batya tha na
Sir ek doubt ha 1,2 tetra cyclobutane Ethan 1-2-diol Ka pinacol pinacolone rearrangement Ka product 1,2 cyclobutane -2-[1-cyclobutyl cyclopentane ] ethan-1-ol hoga kaya Please iska ans bata dijiye please
Hi, ai have a doubt on the 3rd question in the mechanism can we break the bond between the 2 carbon that constitutes the OH group and make it a 10 membered ring .??
In ques no. 6 when we are removing primary alcohol using tscl and pyridine Why a more stable 6 membered ring undergoes ring expansion to become a 7 membered unstable ring because generally a 6 membered ring is more stable than seven membered ring.
But mam ne btaaya h videos me k oh k adjecent position pr positive change aata h to vo more stable hota h ..... actually it's substituted carbocation which is driving force for ring expension 👍
Mam aap J chemistry aap laye h to mere jese students Jo ki pay nahi krrr sakate h vo abhi tak to aap ki videos se study krr rhe but ab vo kese padai krr sakenge uske liye kuch bataeyega please
mam ... e.g group theory complete kraya h aapne youtube pr ...to kya mam app pr whi videos hongi ya aur bhi hongi ,,,,,Agar kisi particular subject ka course purchase krna chahe to kb tk mil jaayengi videos...plz reply
App pe entirely new videos aapko milengi UA-cam and app has nothing to do with each other Koi bhi course aap buy kariye Videos daily basis pe hi upload hongi

One of the best chemistry faculty.. I had ever seen. The content is precise and fabulous. Thanks a lot.
Is this pinnacol in neet syalbbus?

Thank you soo much mam.Really understanding lecture.
From Pakistan🥰 🥰
You are Best teacher of chemistry
Mam aap conceptually mechanism batate ho aache se thank you mam 🙏 😊
best lecturer i have ever seen. thanks alot maam.
This is what the best teaching is...!!!🙏 Thanks alot mam
Jee aspirants also watching this video beacuse ma'am you teach very well 🥰🥰
Yes
Very good mam apka ye lecture very useful
Thank you very much mam your videos are veryful mam😊😊
I was so much involved in lec mujhy laga ma live parh rae hn and i was literally nodding my head and giving you answers🤣
Hhhhhhh
Nice explanation mam 🙏🏼😊
Thanks
Mam u always teach us some new concepts .very nice mam thanq so much . Mam plz make a video on strategy for last month preparation of gate exam.
Thanks a lot mam ap jasa koi b nhi h jo hm sbke liy itna kuch kr rhe Ho god apki hr wish puri krega pkka mam ap hr chij ko deserve krte ho
Thank you 💚
Mam your teaching is just awsm...bohot helpful video
Thnq so much mam bahut easy way mein samajhaya aapne.
Very nice explanation mam 👍
Best lecture ever
Thank you maim, aapke help se mera stereochemistry ka paper bhut accha hua, thanks again maim
My pleasure 🌺
Awesome mam
The best teacher
If u speak slowly then we can understand easily..By the way ur teaching is so good
Thank u very much mam u cleared my doubt
Thanks mam concept crystal clear ho gya
Thanks a lot ma'am!!!
9:51 but mam resonance effects dominates over hyperconjugation and inductive effect, then how the migration of aryl group take place, i think the carbocation will form where phenyle group is present 8:53
amazing explanation
Migratory aptitude
H>ph>r
But book shows ( organic chemistry by bhupinder mehta & manju mehta)
Ph>r>h.
Same question 😢
Mam COOEt will migrate instead of phenyl in 1st example.
Please explain it.
Mam when will you start electrochemistry topic??
Awesome Explanation...!!
Pls explain in English mam.. Very nice ur video
Aapko dekhte hi sister wali feeling aati hai
That's so sweet :)
Thank u mam😊
You are a genius teacher..
Concept clear
Nice vedio.....good morning beautiful mam
Nice mam

Does bsc maths student can pursue for msc chemistry.if yes then how and where did you got admission. Plzz reply??

Mam please answer me what is the force for wanger-meerwein rearrangement....?
Thank u so much
Super class
Excellent mamm..
which book would be best for Molecular rearrangement ?
plz reply madam ...
Sanyal
In between eg 1 and 2 there is an example in ph grp is migrating, and the resulting carbocation formed will be less stable because of EWD (COOet); may be iam wrong can u please check once
Mam in 1st question . When hydrogen will move to the carbocation so it would have +ve charge , it can't take its electron pair with itself because it is less negative than carbon atom
Agr paly e attack k bad stable cation bnna a tow phr migration ki kya zrurt a ?
Hydrogen jb jayega to us per positive charge hoga na ,
thank you
Mam in the last question ⁉️ Where did the two hydrogens of CH2 go?
Ma'am..migrating group order is crct?
Mam jo last vala example hai ma agar h plus ke presence ma hi ch2+ benzylic carbocation nahi bana sakte kynki 3 carbocation se benzylic carbocation jaydea stable hota hai apne starting ke video ma batya tha na
Usme benzene ring nahi hai isliye benzylic nahi banega...
wo benzene ring nhi hai. jo bonds ring pe hai wo asl mai ring k bahar hai. ye pinene hai most probably. u can see it in wagner meerwein rearrangement
But in Kalsi book migrating group sequence is Ar>H>R
Mam why in the presence of acetic acid containing trace of sulfuric acid gives phenyl migration?
Sir ek doubt ha
1,2 tetra cyclobutane Ethan 1-2-diol
Ka pinacol pinacolone rearrangement
Ka product
1,2 cyclobutane -2-[1-cyclobutyl cyclopentane ] ethan-1-ol hoga kaya
Please iska ans bata dijiye please
How will we get to know which intermediate is stable ?
Mam 3 question me jo common bond h do rings ke bich vo break nhi ho skta kya
Is in pinacol rearrangement end product must be ketone formation?
10.15 Phenyl is EWG right?
Mam In Question no.2 why ring change from 5 member to six member please clear my Doubt🙏
Thank you mam naming reaction karva do jam ke liye completely
Beginning is awesome 😂😂😂 aati h toh Q kro!
Nice. ...
Thank u
hlo mam migratory aptitude of phenyl is more than hydrogen
Hi, ai have a doubt on the 3rd question in the mechanism can we break the bond between the 2 carbon that constitutes the OH group and make it a 10 membered ring .??
Nice
conc.h2so4 is not used in pinacole-pinacolone rearrangement.why?
Madam Aromatic ring pr jb Electron donating and withdrawing group lge ho to Migratory aptitude kiska jyada Hoga..ye v bta deti books se 👍
Mam than what is the difference between glycol and pinnacole
Mam migration ka order ph H me hoga kya
Neeraj Kumar rajak very nice mam

In 10;30 if carbocation is unstable then why we do migration????
