sir in the first que when we get nucleophiic benzene ring, why will it attack O2? doesnt O2 have free electrons around it..thus nucleophile would not prefer to attack it right?
Bhaiya in the video at time 8:52 you R doing pinnacole pinnacolon ,so according to migratory aptitude instead of methyde shift there should be hydride shift
Sir how does Grinard Reagent chooses between C=O and same come compound containing O as hetero atom ?which place will it attack.. I mean which bond is weaker?
videos bahut helpful h. :) continue making the same. if possible pls make a video on coordination compound,thermodynamics and probability before 10th may !
bhaiya pls try and upload a video on biomol.and polymers before Jee advanced 2017 as these two topics are very crucial wrt jee and it would be of a great help. . .and Bhaiya ur way of teaching chem is just fabulous . thanks a lotfor all these beautiful video s.....
Sir, I have been watching all your chemistry and maths videos .It would be a big help if you could explain physics also (EMI, fluid mechanics, modern physics,wave optics) The way you explain is just amazing. Thanks again
Sir at 15:33. H30+ is 2nd reagent right.So why are You taking it before the complete reaction of LiAlH4.i.e First the Compound should be attacked with 4 H- and Only then H3O+ should be considered right?.Please Clarify this.
He used the h+as the catalyst as we know every catalyst has to be removed after occurrence of any organic reaction he did me shift to remove h from oh attached to the carbon. If he didn't shifted the methyl and removed h+ from the adgecent carbon he will get an unstable reaction intermidiate.hope you found it useful
Very good video, keep it up. Could you suggest me more UA-cam channels like yours. Preparing for Jee mains through self study. Need to follow good channels like yours in
the way u represent these reaction ,,,,I swear no one can represent I ve seen u r the best bro. please what u think important about thermodynamics please upload
Dear sir..will you please provide videos on physics ,chemistry specified to state public service commissions...the questions that were asked in the particular examination is very static and factual..almost 80 percent.
Too late to answer but just for the sake of other people, the methyl shift takes place as carbcation is stable on the 1st carbon and then plus charge shifts to adjacent carbon and simultaneously O donates its lone pair, and then h+ gets removed. He shortened the mechanism just for sake of simplicity.
Sir lone pair of chlorine is in resonance with benzene so how can we use mg in presence of ether as u told that it is weak and it will not form grignard reagent
sir at 7:46 (approx ) in the example which you were discussing , there is an alcohol already formed . alcohol's hydrogen is acidic . will the second mole of grignard reagent choose to abtract the acidic hydrogen ?
sir cld u plz upload a video on youtube of the imp ques to be done from the cengage books and what's the right way to read them. hope u won't disappoint us.
sir but while shifting takes place methanide shift is lot slower than hydride shift due to the bulky nature of methyl group and moreover if you shift the hydrogen you get a even more stable carbocation with three extra hyperconjugative structures along with the resonance from oxygen . is my logic wrong ?

great vedeo sir.please aldehyde ketones and acids ki go sari reaction Kara do
Nice very nice vedios by u thanks brother
Great work ..best explained ever...keep on doing it....thanks
Bhaiya at 8:31 why did you do methyl shift ?
It is already a 3° carbocation and after Me shift it turns into 2° carbocation.
??
He used the h+as the catalyst as we know every catalyst has to be removed after occurrence of any organic reaction he did me shift to remove h from oh attached to the carbon. If he didn't shifted the methyl and removed h+ from the adgecent carbon he will get an unstable reaction intermidiate.hope you found it useful

Where will d grignard attack if both ketone and ester group is present..ppplzz say
deserve 100000++++++
+A J thanks.
You are a genius
At 8:10 tertiary carbocation is more stable, then why methyl shift will take place?
Too late to answer but just for the sake of other people, the methyl shift takes place as carbcation is stable on the 1st carbon and then plus charge shifts to adjacent carbon and simultaneously O donates its lone pair, and then h+ gets removed. He shortened the mechanism just for sake of simplicity.
But the 2 degree. Carbo action was more stable then why wont shift decrease its stabilty
Also why dint the h shift ?
@@jasjappansingh2170 because stability due to lone pair is more than anything else
@@meetshah6538 but instead of methyl shift, hydride shift could have taken place according to migratory shift order

please upload videos on EMI and Magnetism asap its very urgent
in your 3rd point which reagent you have used along with mg ?

bro at 8:45 in that reaction why there cant be hydride shift
Same doubt
Very helpful, thank you very much
Plzz upload videos on phenols and their preparations plzz

Really need it. Thank you!😊
Sir plzzz make the video of nulecophile and electrophile
Will be thankful to you forever
8:40 , the carbocation was already 3degree
Then why rearrangement take place??
Plz explain.

Sir lone pair of chlorine is in resonance with benzene so how can we use mg in presence of ether as u told that it is weak and it will not form grignard reagent
Sir you got 115/120 math marks in mains can you upload videos on maths for mains and advance
sir I m NEET aspirant I found these to be smwat tough ACC to NEET

Sachin Rana - IIT Bombay Hats off to you sir..
sir at 7:46 (approx ) in the example which you were discussing , there is an alcohol already formed . alcohol's hydrogen is acidic . will the second mole of grignard reagent choose to abtract the acidic hydrogen ?
+ganesh nagarajan that's awesome thinking. But since we get the protic solvent later; we need to proceed with the reaction.
how sir . we first hyrdolyse it and then put in the next mole right . so when an alcohol is formed doesnt acid base reaxn favour over substituition ??
At 7:41 won’t the second R- try to snatch H+ from 2 degree alcohol formed, as R- is a strong negative charge.
Nice video sir
sir cld u plz upload a video on youtube of the imp ques to be done from the cengage books and what's the right way to read them. hope u won't disappoint us.
these questions are very hard.. is such questions asked for neet??
Plz upload for ether n phenol toooo
Bro is this sufficient for theory.
sir at 8:50 (approx) , wont hydride shift take place as in pinacol pinacolone rearrangement ? isn't hydride shift easier than methanide shift?
+ganesh nagarajan no. The group which is more releasing has a higher chance of shift.
sir but while shifting takes place methanide shift is lot slower than hydride shift due to the bulky nature of methyl group and moreover if you shift the hydrogen you get a even more stable carbocation with three extra hyperconjugative structures along with the resonance from oxygen . is my logic wrong ?
@@ganeshnagarajan5488 you are absolutely right bro

VERY GOOD VIDEO OF ALCHOLS
pllzz answer me soon that is this revision lecture is enough for the neet student and covers all the rections
+Parshvi Nahar yes to a certain level it is enough. You can check out my notes.
sir at 8:19 according to migratory shift order hydride shift should occur or is it the way you did?
yeah i think its wrong
hats off bro 😍😍🙌
Sir I have a doubt that when to attack H- on Oxygen atom in ester part
bhai aapke concept aur unko batane ka style dono kafi diffrent aur bahut mazedar hai....bhai plz solution ka vdo upload kar digiyae na plz...

lv u sir
very interesting lecture
how mg/et2o broke the resonance stablize bonds
At 8:10 the tertiary carbonation I s more stable the why methyl shift😕
Backbonding
Thanku bhaiya
Brother at 8:35 why did you perform a methyl shift even though H- ion ( hydride ion) is also present?
it should be an Hydride shift right?
plz reply
