Predict the stereochemistry of nucleophilic attack on carbonyl compounds with the help of Felkin Anh Model and Cram's Rule easily. Detailed explanation.
Sir, u said that the 2nd example is syn product. But in clayden text it is anti. By referring Clayden text book after the nucleophile attacks through the burgi durnitz angle, through the rotation we put the largest carbon chain group in the plane of the paper. Then draw the product like the starting material. In the 2nd example after the attack of nucleophile we write the Newman projection. Then rotate the back carbon to place the largest carbon chain ethyl group in the plane of the paper. After the rotation the OH group become below the plane.
Sir please solve this question If a graph of ln t1/2 vs ln a0 is ploted and it has a slope 2. What is the order of reaction? ln - natural log t1/2 - half life a0 - initial concentration
Sir...please upload video on absolute R/S configuration of biphenyl compound and allene and no. of stereoisomers of compound.These topics are important for GATE and every year a question came from those topic.Thank u
Sir,a question is asked in gate 2016 paper question no.22 to predict the transition state,how can we use Felkin Ahn model for this type of question....
Hello sir ..is this felkin Ahn model only used for aldehyde or keton? Or it is also used for acid , ester which is adjacent to chiral carbon?? I am little bit confused ...
sir please make a video on chelation control in felkin ahn model.. i do not understant this ... sir bcz the way of your explanation is superb sir please explain chelation control in felkin ahn model ..
I think ur specialization is in organic chemistry can u help me in studying modern organic synthesis by carruthers chapter 3 i.e. pericyclic reaction.....its stereo is little bit complicated
Hi...sir give me one answer that ....if the starting material contain one stereogenic centre and a prochiral carbonyl gr. then reaction at prochial centre will always be diastereoselective?..please give answer in detail if possible.
sir i have a confusion that when u draw both the conformations on Newman projection to predict which conformation will allow preferable nucleophilic attack then how do we maintain the configuration of the chiral center?
sir whether i have subscribed to your channel or not ? It is just by clicking red subscription button know sir ? because im not too good in technology ,while informing others I have to explain so....
my suggestion to all subscribes. solve these problems by crams rule, bcz of crams rule solving ths problems becomes very easy to a great extent. but give explanation only through felkin model bcz logics are more important than rule. some additional point to felkin model. y we place more bulkier grp perpendicular to carbonyl.its due to effective overlapping of [pie]* to [sigma]* to form new lumo of lowest energy.
please don't take the lecture lengthy ...just focus much on topic rather than other things... because you are teaching amazing..then flow of studying breaking when you talk about other things....
No problem sir ! Aap Hindi bol sakte ho ! Hindi is best ❤ Edit : Jo ye video Hindi me hota to aap khan sir ki jagah hote 😅 par koi baat nai Well Done ✅ 5 sal pehle ka hai to theek hai.
I think subscribing others to your channel is the best way to thank you for these crucial lectures..

Sir what are u the preparation for net
Thanks for this video on felkin anh model. It would be more helpful if u could make a video on Zimmermann traxler model
Sir why is falkin an model necessary,the stereo of attacking nucleophile also decided by cram rule.plz explain
Sir , does finding out syn and anti of conformation is important or simply shud write the product....???...
Sir fantastic video and great explanation!! Is it present on the channel an explanation about Zimmerman-Traxler TS?
sir ...Beacuse of you im solving felkin Anh model problems...thanks alot... Keep us Guiding :)
sir how to distinguished between the cram's model and felikn ahn model??
Congrats fr 4k subscribers sir.i hope u get many more
Great sir .. understood concept.. which was difficult to understand. Thnku
Sir please solve this question
If a graph of ln t1/2 vs ln a0 is ploted and it has a slope 2. What is the order of reaction?
ln - natural log
t1/2 - half life
a0 - initial concentration
Sir in your first example you show nucleophile in plane how it is possible .. aapne starting H se ki plane me fir H plane me aainga na
How you tell phenyl in the first example @6:58 is ri8 ?
I have a small doubt.when when could be crams model apply what is the difference between felkin anh model and crams model.
great efforts and ur teaching skill is awesome...
Sir...please upload video on absolute R/S configuration of biphenyl compound and allene and no. of stereoisomers of compound.These topics are important for GATE and every year a question came from those topic.Thank u

Hello sir ..is this felkin Ahn model only used for aldehyde or keton? Or it is also used for acid , ester which is adjacent to chiral carbon?? I am little bit confused ...
Ok sir ...waiting thank you sir
Sir make video of list of topics through which we can get 110-120 marks in csir net as now there is less time for dec exam.
I have one doubt sir.while looking how phenyl group at right hand side.is it at left side?
Yes sir...I got it.sorry
when s phenyl propanal react with MeMgBr what will b the product u give the first example it is R phenyl propanal please
sir please make a video on chelation control in felkin ahn model.. i do not understant this ... sir bcz the way of your explanation is superb sir please explain chelation control in felkin ahn model ..
Why is your black board in motion
I think ur specialization is in organic chemistry can u help me in studying modern organic synthesis by carruthers chapter 3 i.e. pericyclic reaction.....its stereo is little bit complicated
sir please give the name of both product R and S first example of your this video i.e. R phenyl propanal ; thanks all video is useful for me
Hi...sir give me one answer that ....if the starting material contain one stereogenic centre and a prochiral carbonyl gr. then reaction at prochial centre will always be diastereoselective?..please give answer in detail if possible.
Thanks a lot
Sir i have covered about 25% of syllabus and 2 yrs paper.So now how many hours should i study to crack jrf?
Super explanation sir but u teach very well explain felkin anh model by chelation effect pls sir
Sir aise toh Nu-plane m show hora..attack toh above ya below hoga na
Informative video sir plz make video on quantum chemistry
Very nicely explained 👌
sir y u keep Opposite side in your 2 video it can b between the NBr2 and R group
very nice videos sir all referred by Jagadeesh
Nice video sir.....good to understand......
Cram rule in jam syllabus or not?
Thanku for explaining this😃
Hello sir, whenever you are replying for my comment Im getting it as highlighted reply .what does it mean sir?
Big brother (sir), I kindly request you to say that please upload about NEPHELAUXETIC EFFECT.I AM PANKAJ FROM JHARKHAND
sir i have a confusion that when u draw both the conformations on Newman projection to predict which conformation will allow preferable nucleophilic attack then how do we maintain the configuration of the chiral center?
sir make a video on assymetric synthesis
sir whether i have subscribed to your channel or not ? It is just by clicking red subscription button know sir ? because im not too good in technology ,while informing others I have to explain so....
Is this useful for IIT JAM ?
Gate chemistry yeah..I am thank you sir..for this..
that should be 109 degree how can you say tha 120 degree as it is sp3 hybridise carbon 27:23
sir upload video about quantum chemistry.plz...
my suggestion to all subscribes. solve these problems by crams rule, bcz of crams rule solving ths problems becomes very easy to a great extent.
but give explanation only through felkin model bcz logics are more important than rule.
some additional point to felkin model.
y we place more bulkier grp perpendicular to carbonyl.its due to effective overlapping of [pie]* to [sigma]* to form new lumo of lowest energy.
Hii
Sir plz explain 2015 June booklet a 114 bit
Sir explain felkin anh model chelation effect pls sir
sir if stereo is not given for Alpha c than how it is solved explain by taking one example plz
thankiu very much you are my salvator
very useful as usual
please don't take the lecture lengthy ...just focus much on topic rather than other things...
because you are teaching amazing..then flow of studying breaking when you talk about other things....
but we got extra knowledge from extra things
this process is little complicated and take more times.
Thanks sir
Thank You ^^
thnku sir...
THANKS SIR
No problem sir ! Aap Hindi bol sakte ho ! Hindi is best ❤
