Awesome work sirrr....it wil be tht much helpful for us..

[@shaswatakundu3935]

What about the Nitrogen(I =1) in N4P4 Cl4(Nme2)4.

[@han-rw1bg]

Sir can u explain the naming of phosphazene structure. 2,2,6,6 signifies what?

[@sandipmondal2837]

very helpful video.. thank you

[@anuanitha6321]

Sir can u explain this the no of hyperfine lines obtained in p31 nmr spectrum of pf2(15Nh2)2 H

[@saptarsikumar3057]

Sir app ki explanation bohat accha hi...In 20-25 min. Explain basic concept as well as question...Plz stay with us

[@AllBoutChemistry]

Thank you 😇 I'll try yo make more helpful videos 😇😇

[@nikhatsheikh1334]

Very nice sir👍👍..please solve questions on reductive elimination

[@Ayush-cs5tw]

Thank you sir . I was too confused before this video 🤷❤️❤️

[@alkasahu3883]

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

Thank you sir 💐

[@birendranathbair9913]

Thank you very much. Good video

[@AllBoutChemistry]

thank you :)

[@Real..Intertainment]

sir in last p nmr. how many no.. of signal. in pH3Bcl3.

[@KrishnaSharma-ik3sm]

Thanks sir 🙏🏻🙏🏻

[@chandragollapalli1308]

Thank you very much sir

[@palakdang4825]

Sir why did the boron show equal splitting of signals? Pleaseelaborate with some other example so

[@akankshaawasthi4875]

Awesome 👌👌👌👌👌👌

[@alkasrivastava4056]

Sir please make a video of 1H NMR of inorganic molecules....

[@vvsciencepedia1969]

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

[@dr.nagarajurajana2867]

Nice presentation 👍

[@tandrimabanerjee6617]

Plz provide the link of 19 F NMR

[@chandrashekarhb3455]

Hi, how many P-31 NMR signals are shown by the P(CF3)3 molecule? will it be singlet?

[@anirbandutta3246]

sir why we are not counting the effect of chlorine in in june 2017 question of 31P NMR spectra 2,2,6,6..

[@tamilenter213]

I value is zero

[@karinas.1320]

@@tamilenter213 No it has nuclear spin of 3/2

[@windofhappiness]

Sir what about N..in N4P4Cl4.. directly 2j coupling with P without considering 1j with N first ...plz Reply sir...

[@srikanthreddydaggula4751]

Very nice sir thank u so much sir

[@tamilenter213]

Great anna😘😍😘😍

[@dileepkumarsaini8331]

Thanks sir

[@shafnat3262]

N4P4Cl4 (NMe2)4 has a different structure when u explained in unacademy... Why is it so?? Plzzzz plzzz do reply

[@chemist1703]

How to draw this structure sir?!😮

[@gaikwadswapnil6021]

Sir plz share tricks and exceptional cases related to co-ordination chemistry

[@AllBoutChemistry]

Alright 👍

[@najranaahmed3698]

Why NMe2 is not counted in phosphorus neighboring group

[@sakshimehta7787]

Sir iske theoritical portion ki bhi video bna do and sabhi spectroscopies ke theoritical portion ki bhi

[@AllBoutChemistry]

Alright 👍 I'll make them soon,

[@AB-et5vi]

Sir will you please make a video on 19F NMR..please

[@AllBoutChemistry]

Alright I'll try to make one 👍

[@sss12644]

Why in N4P4CL4 (NMe2)4 question,1J,ie,N doesnt couple with P?please explain

[@karthikkd3471]

Bcz since nitrogen is NMR inactive due to its has even number of electrons and the total spin is zero

[@irinelizabeth5639]

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?

[@arunavamisra1455]

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?

[@ishamittal6941]

Because the coupling constant of P-H is more than P-B so first follow splitting of P-H then P-B

[@AllBoutChemistry]

Nicely explained @Isha Mittal

[@muthumuthu7946]

Tq sir.Sir how to calculate the spin value for coordination compounds.? Pls explain sir..

[@AllBoutChemistry]

which spin value you want to calculate? I mean nuclear spin value or electron spin value.

[@muthumuthu7946]

Sir I need to know nuclear spin as well electron spin..like Zn2+,Cu2+complexs

[@snehlatakatheria7212]

Thank u sir.... Sir coordination ki Aur Vedio banaya Kya or its over

[@AllBoutChemistry]

Maybe I'll. Make few more on MLCT and LMCT

[@ruchi5178]

Subscribed the channel 😄

[@snehlatakatheria7212]

Thank u sir

[@AllBoutChemistry]

You're welcome 😇

[@snehlatakatheria7212]

Sir.... Humble request MLCT LMCt Vedio... Please upload👍

[@AllBoutChemistry]

I was already preparing for that, video is uploaded, kindly check it :)

[@gollavineetha3482]

sir,in Ap SET they are not mentioned I(spin multiplicity) value .how to find I value for diff atoms.please teach

[@AllBoutChemistry]

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

[@gollavineetha3482]

great,thanks sir

[@IT-Masterminds]

Pls do gate exam solved papers

[@alkasahu3883]

Sir sir please this question my exam will be held on Monday

[@04SATHEESH]

Why don't you consider phenyl hydrogen in the second question of PPh3BH3? Any reason. Pls reply

[@karthikkd3471]

There won't be any hydrogen bro just think about it

[@gurjotkaur4049]

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

[@AllBoutChemistry]

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.

[@gurjotkaur4049]

@@AllBoutChemistry thankeww sir

[@RamRam-oi7gm]

sir can u explain chemical kinetics with problems

[@AllBoutChemistry]

Video on Chemical Kinetics is already there. Plz watch it.

[@AllBoutChemistry]

Here's the link: kzbin.info/www/bejne/nmPaZZiLjNiBosk

[@premnathdas1823]

Sir why P was not splitted for B first then for H..if it will thn should be option 1..

[@knowingchemistry735]

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.

[@vikassrivastav9942]

Sir what about coordination chemistry lecture series?

[@AllBoutChemistry]

I've posted 3-4 videos on coordination chemistry already.

[@vikassrivastav9942]

But there are much more topics in coordination chemistry.

[@AllBoutChemistry]

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.

[@vikassrivastav9942]

I appreciate your job. And waiting for next video desperately.

[@AllBoutChemistry]

Thank you, 😇 Will be uploading very soon

[@anupampal190]

Sir...plz make more video on physical chemistry...

[@AllBoutChemistry]

OK 👍

[@anupampal190]

What isThe best book of physical chemistry??sir plz suggest this...

[@AllBoutChemistry]

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. kzbin.info/www/bejne/r6bFXqlmest8sJI

[@myfamily4048]

Why two figure of 1:1:1:1 & 1:3:3:1 is given in option (3) of your last question?

[@harshitatrivedi1402]

Sir is this topic included in msc entrance exam??

[@AllBoutChemistry]

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.
