In the last question, why you don't consider first the coupling between P and B to give first 1:1:1:1 peak then it will splitted be the H to give 1:3:3:1 peak of each equal intese line?
I agree and I will. Make videos on that too, Making videos on same topic is a tidious practice so I just uploaded this, I will definitely make videos on coordination chemistry soon.
It depends on which topic you want to cover. I've made a video on books to follow, you cab watch this video, I've discussed about many books alongwith the topic which is given nicely on them. ruclips.net/video/yub-v0EfIz0/видео.html
Sir please solve this question ' an nmr machine with a magnetic field of 2.73 Tesla was set for PMR at 100 MHz.Calculte the radio frequency required to record 31 P nmr Spectra on this machine when it's field strength is improved to 10.92 Tesla.Given gyromagnetic ratios 1 H nmr = 26.75 & for 31 P nmr= 10.84
plz sir make on video iron sulfur protein .......with explanation how to oxidised his state with oxygen and or by taking electron. .... everything related to it
This topic you will see in most of the M.Sc Entrance Exams including IIT JAM, BHU PET, DU, HCU etc. every good university conducting M.Sc Entrance will include this topic in their entrance exam.
If you draw the structure of complex, you will get trigonal bipyramidal structure. having two axial F, and two equitorial F alongwith N(Me)2 on the equitorial plane. Now at high temp all F will do fluxonal behaviour and they will be equivalent. so you will get (2nI+1) where n=4 for 4 fluorine, so total 5 lines at high tem. at low temp. the axial F will be different from eq. F, so you will get (2nI+1)x(2n'I+1) where n=2 and n'=2, so total 9 lines at low temp. put I=1/2 in the formula.

What about the Nitrogen(I =1) in N4P4 Cl4(Nme2)4.
Sir app ki explanation bohat accha hi...In 20-25 min. Explain basic concept as well as question...Plz stay with us
Thank you 😇
I'll try yo make more helpful videos 😇😇
sir why we are not counting the effect of chlorine in in june 2017 question of 31P NMR spectra 2,2,6,6..
I value is zero
@@tamilenter213 No it has nuclear spin of 3/2
Because quadrupole magnetic moment effect (sorry for late answer)
Why in N4P4CL4 (NMe2)4 question,1J,ie,N doesnt couple with P?please explain
Bcz since nitrogen is NMR inactive due to its has even number of electrons and the total spin is zero
No....14N has atomic number 7 and I value is 1....Is this not considered because coupling is weak for an I=1/2 system with I=1 system?
Awesome work sirrr....it wil be tht much helpful for us..
In the last question, why you don't consider first the coupling between P and B to give first 1:1:1:1 peak then it will splitted be the H to give 1:3:3:1 peak of each equal intese line?
Because the coupling constant of P-H is more than P-B so first follow splitting of P-H then P-B
Nicely explained @Isha Mittal
Awesome 👌👌👌👌👌👌
How to draw this structure sir?!😮
Sir why did the boron show equal splitting of signals? Pleaseelaborate with some other example so
Great anna😘😍😘😍
Nice presentation 👍
Thanks sir 🙏🏻🙏🏻
Sir can u explain the naming of phosphazene structure.
2,2,6,6 signifies what?
Thank you very much. Good video
thank you :)
very helpful video.. thank you
Sir iske theoritical portion ki bhi video bna do and sabhi spectroscopies ke theoritical portion ki bhi
Alright 👍 I'll make them soon,
Sir what about N..in N4P4Cl4.. directly 2j coupling with P without considering 1j with N first ...plz Reply sir...
Why NMe2 is not counted in phosphorus neighboring group
sir in last p nmr.
how many no.. of signal. in pH3Bcl3.
Thank you sir 😊
You're welcome 😇
Sir what about coordination chemistry lecture series?
I've posted 3-4 videos on coordination chemistry already.
But there are much more topics in coordination chemistry.
I agree and I will. Make videos on that too,
Making videos on same topic is a tidious practice so I just uploaded this,
I will definitely make videos on coordination chemistry soon.
I appreciate your job. And waiting for next video desperately.
Thank you, 😇
Will be uploading very soon
Sir will you please make a video on 19F NMR..please
Alright I'll try to make one 👍
N4P4Cl4 (NMe2)4 has a different structure when u explained in unacademy... Why is it so?? Plzzzz plzzz do reply
Plz provide the link of 19 F NMR
Sir plz share tricks and exceptional cases related to co-ordination chemistry
Alright 👍
sir can u explain chemical kinetics with problems
Video on Chemical Kinetics is already there. Plz watch it.
Here's the link: ruclips.net/video/h2w4eUWsNlg/видео.html
Very nice sir👍👍..please solve questions on reductive elimination
Thank you sir . I was too confused before this video 🤷❤️❤️
Why don't you consider phenyl hydrogen in the second question of PPh3BH3? Any reason. Pls reply
There won't be any hydrogen bro just think about it
Tq sir.Sir how to calculate the spin value for coordination compounds.? Pls explain sir..
which spin value you want to calculate? I mean nuclear spin value or electron spin value.
Sir I need to know nuclear spin as well electron spin..like Zn2+,Cu2+complexs
Sir please make a video of 1H NMR of inorganic molecules....
Sir can u explain this the no of hyperfine lines obtained in p31 nmr spectrum of pf2(15Nh2)2 H
Thank u sir.... Sir coordination ki Aur Vedio banaya Kya or its over
Maybe I'll. Make few more on MLCT and LMCT
Sir...plz make more video on physical chemistry...
OK 👍
What isThe best book of physical chemistry??sir plz suggest this...
It depends on which topic you want to cover. I've made a video on books to follow, you cab watch this video, I've discussed about many books alongwith the topic which is given nicely on them. ruclips.net/video/yub-v0EfIz0/видео.html

Subscribed the channel 😄
sir,in Ap SET they are not mentioned I(spin multiplicity) value .how to find I value for diff atoms.please teach
You should remember I value for some atoms like ¹H, ¹³C, 15N, 31P and many other are there... I'll include them in my video on EPR spectroscopy
great,thanks sir
Sir why P was not splitted for B first then for H..if it will thn should be option 1..
Because in ques it is given that J value for PH is more than PB so H will couple i.e split P signal first.
plz sir make on video iron sulfur protein .......with explanation how to oxidised his state with oxygen and or by taking electron. .... everything related to it
Hi,
how many P-31 NMR signals are shown by the P(CF3)3 molecule?
will it be singlet?
Sir.... Humble request MLCT LMCt Vedio... Please upload👍
I was already preparing for that, video is uploaded, kindly check it :)
Sir is this topic included in msc entrance exam??
This topic you will see in most of the M.Sc Entrance Exams including IIT JAM, BHU PET, DU, HCU etc.

sir in 31pnmr what will be the no of lines in PF4N(CH3)2 at room temperature and low temperature if N and H do not couple ?? sir please give the ans
If you draw the structure of complex, you will get trigonal bipyramidal structure. having two axial F, and two equitorial F alongwith N(Me)2 on the equitorial plane.
Now at high temp all F will do fluxonal behaviour and they will be equivalent. so you will get (2nI+1) where n=4 for 4 fluorine, so total 5 lines at high tem.

put I=1/2 in the formula.
@@AllBoutChemistry thankeww sir
Sir Don't just tell and mark 1 option speak about other options also!
Sir sir please this question my exam will be held on Monday
Why two figure of 1:1:1:1 & 1:3:3:1 is given in option (3) of your last question?
chemist-try
