I was having exam today and this video helped me alot i didn't understand all these factors when i studied myself but when i watch this video now everything is clear to me big big thanks to you
You are greattttt sir... You saved my life. I studies whole NMR from your videos great 👍
you are saving my life! god bless you
Complex topics explained by you in just a blink of eye.. Hats off sir. HUGE RESPECT
you had a very huge knowledge sir and your way of representing topics are incredible.
Glad to know 👍🏻
Thank you for the appreciation.
Keep studying and Share the Video Links with your friends and help us to spread the knowledge. ❤️💜💙💛💚
Hoping for doing well in next examinations. Thank you so much sir for crystal clear explanation. 🙏
Nice explaination sir very helpful to gpat preparation students sirr 🙏🙏🙏🙏
EXCELLENTLY EXPLAIN THE TOPIC
As usual awesome explanation
Ur explanation very good easy to understand tq sir
I am teaching as it is my students..thank u so much
Thank you so much sir. Please share the video links with your friends and students too.
Thank you for the appreciation. 🙏
Sr aap genious ho great sr
Its very helpfull
Sir..ur really expert...
very helpful, thanks sir
Thank u so much sir
Ur video is too nice to explain u
Awesome sir...this video very helpful.

Thank You for the appreciation.

Thank You Sir
Thank sir 😄🍁☀
thank u so much for sharing with us....nice explanation
Well explained 👍
Very Well explained sir
Sir if we take two compounds in which one has primary carbon and other has tertiary carbon than which compound has higher delta value and why it has higher value than other one?
Sir please reply
3° as due to field effect.
@@himanshurawat8078 no because ter has no proton its all three methyl appear at same one signal there intensity will be high
Thank you sir...
Thank you so much 🤩🙏🏻
TQ sir
best explanation 😊😊
Thank you for the appreciation.
Keep Watching and Share the Video Link with your friends and help us to spread the knowledge. 👍
Sir plz try to write little bigger.. bdw your explanation are really understable
Thank you so much.
I will try in upcoming videos.
Meanwhile bhi can view at 720p or 1080p it will be clearly visible.
Thank you so much sir
Nice
You are the best
Sr very interesting character sr
V alvs following your explanation sr
Is there any video about advantages of NMR ?if yss plz can someone send me the link . Tomorrow is my presentation on it
I have not uploaded that topic.
Oh ok
FT.NMR advantages and NMR advantages are same or different?just confirm me that point plz
@@ZahraZahra-ri2ix NMR is used generaly but FTIR also aspect of the way we use in nmr both advantages are same some how
excellent lacture sir but 20 min video contain 9 adds which are quite disturbing during lacture.
nice video
thank you bro
why chemical shift value of 'C-H' of acetylene is lesser than ethylene
Acetylene have 2 π bonds so proton are more shielded then ethylene because ethylene have one π bond..ok..
due to magnetic anisotrophy
Sir prhaya to buht acha hay shayd apki wja sey NMR mey pass krlu..lekin aik hi shirt pehn sari vedios bna li 🤣😅
The delta value for sp hybridized carbon is 2-3 ppm which is opposite to actual obesrvation
in ethyne it is due to magnetic anisotrophy read it you will understand reason
Make the video for shilded deshilded topic in nmr
Please go through the complete playlist of NMR Spectroscopy , It's already available in our channel, everything is discussed.
Sir please explain thermal methods
Sir thoda hindi me explain kr diya kriye aur achche se smjh aa jayega
Good explanation sir ...
Will you upload a video on problems asked in CSIR NET related to NMR coupling constants
Already uploaded complete playlist. Please watch all 18 videos
Sir yy chemical shift scale starts from right ?
it is a refrence scale not always starts from rigth because in som more sheilded protons then TMS appear roght to 0 value
Sir I need nmr problems in Hnmr
Sir could you please tell me what is S character?
It is just the percent closeness of electrons in an orbital towards the nucleus..
As we know that the S orbital is nearer to the nucleus compare to P orbital, hence we take percent S and percent P character of the hybridized orbitals through comparison with pure S orbital (closer to the nucleus) and pure P orbital ( relatively farther from the nucleus).
it is simply involvement of s orbital percentage in hybridised orbital
Sir deshielded upward field hota aa ???
Down field... Clearly written in the video
Thank you sir for your valuable videos
Welcome!!!!!!!
Keep Watching and Share the Video Link with your friends and help us to spread the knowledge.,
👌👌
Sir plss Hindi mae padha do ...nhi hota English apki toh kyu Krna...Hindi mae zyada acche sae smjha payenge
Sir koucham slow ga explan cheydi for telugu medium students
Does magnetic frequency also affects chemical shift
Yes
written very small its quite difficult to view what is written
Vijaya Maurya
I will try to write in bigger handwritten in my upcoming videos.
Till now you can watch at HD (1080p) it will be visible or you can take screenshot and convert it into PDF.
Thanks
This vedios are reliable for exam point of view?
😂😂 That will be decided by you.
FYI it is also useful for National Level Exams like GPAT, Drugs Inspector, Pharmacist etc.
@@pkclasses100 btw nice detailed explantion!!
What could be maximum chemical. Shift value
It will be 10 or 12 generally for 1H-NMR
Ty sir
Wow
Writing is not clear 🤷♀️
💯🤘🙏
Sir apka naam ajeeb hai
Ab name me kya rakha hai... Kaam pasand aana chahiye 😍😂
Thank you sir
Thanks alot sir
