Sir in all thr cases in examples you gave larrge group and electronegative group is same but what if electronegative and large grp are different in a compound then which group we have to consider electronegative group or large group syn or anti to carbonyl group please clear it
If both electronegative grp and large are there in the question then you have to consider the electronegative grp for syn or anti w.r.t carbonyl grp.And u must take the electronegative grp in plane with carbonyl.
Sir when -CHO direction was not mention ..how to determine syn or anti of large or Z grop to -CHO group..please see the probleam on carruthers..on page no -47 main group chemistry...
My question is related to anomeric effect. In case of glucose their are two anomers beta and alpha . Beta is more stable. They occur in ratio 64:36. My question is that though beta is more stable then also why alpha occurs in such high percentage?what is the reason for alpha anomers more stability?
Sir, in EtMgBr....will Mg here not chelate with the reactant?? In your former video, you have mentioned that Mg will chelate...please clear my doubt sir...
sir as u told that when chelating grops will b there den v ned to reverse the actual cocept.i.e when larger gp is syn then nuclphile will attack to the same direction of small group...but in lst example u hav taken medium grp in consideration instead of small gp..let me know how? .plz
one of the best video of this channel.
Really helpful video..as i am preparing for dec exam..thanks a lot
Indeed the best teacher
Very helpful vedio for me sir...tnkq..very clearly explanation....🙏👍👍
Awesome sir..before ur trick i am very confused about crams and felkin..now i can solve crams and felkin problem easily in exam.
Wow wow wow... Very easy... Tqqqq

Sir can you reccomend textbook to study felkin and list of chemical can do chelation

In last example the product which we have got in that also we have to bring Et in the plane...?

Sr why we push the Et grp ??
Nice thank you sir
Great
Sir, in EtMgBr....will Mg here not chelate with the reactant?? In your former video, you have mentioned that Mg will chelate...please clear my doubt sir...
Mg cannot able to form chelate here as the Z grp is phenyl.Chelation takes place if the Z grp has lone pair electron(eg: OR,SR,NHR etc).
@@amitkumarguin6759 thank u so much
他裡面並沒有其他有孤鍵結電子對的可以去打Mg
Amazing trick ... it's working perfectly
Very much helpfull video .......thnks
Sir please explain 2018gate que no 26 based on this model ..apke method se ans sahi nahi aa rha..plz guide me
Best best best ...
You are the Best ☺👌. Thank you so much sir.
Sir there is a question on crams rule in 2011 question paper there is a problem in solving it
Sir gate 2018 qn no.26 can't be solved by this tricks... please clarify...
It is indeed a super_duper trick.
Thank you vert much sir
Very much thanku you Sir...
Sir in 2nd eg. Suppose the large grp(phenyl) is not in the plane what'll do...!! whether we need to change to in the plane ????
Yes rotate it to bring the phenyl(large grp) in plane same with carbonyl.
Sir in last que..as stereochemistry not given then we will rearrange etyhl or not to get the product?
Same query
Thanks alot sir
Thank you so much
Thank you sir😊
Can you solve 2016 Dec question set b Q.104 related to felkin- anh model?
That is not felkin anh model ratrher Zimmerman taxler model

He did it by mistake
Thank u sir
Sir I qualify CSIR NET EXAM
LS RANK- 9
Your video's are very helpful sir
Congrats
Can only clayden for organic be helpful for organic in xm..??
