Anisotropic effect (Magnetic Anisotropy) | Aromatic compounds, Alkenes, aldehydes and Alkynes
มุมมอง 1.8K2 ปีที่แล้ว
Magnetic anisotropy means that there is a "non-uniform magnetic field". The effects of currents due to circulation of π electrons in other parts of the molecule on shielding and deshielding are called anisotropic effects and they depend on the orientation of proton relative to the induced magnetic field. This anisotropic shielding, or anisotropy, leads to regions of shielding and deshielding ar...

Pyranose and furanose form of D-Fructose
Why is β-D-glucopyranose more stable than α-form
มุมมอง 3.4K2 ปีที่แล้ว
Stable conformation of 6 membered ring is chair form. Pyranose form is converted to chair form In β-D-glucopyranose all -OH groups and even -CH2OH are at equatorial positions, hence more stable. Therefore β pyranose form of glucose is more stable and is abundantly present in nature.

Very nicely taught madam. Completely understood about activated sludge process
Thank u so much mam❤
Best video on mass spec MW determination
Namo buddhay namah🙏🏿🙏🏿🙏🏿🙏🏿
Thank you, it was very helpful
It is oligo sacharide synthesis
This is the best video I've ever seen on this topic. I'm so happy that i wrote this comment not even completing the whole video. Thanks, thanks a tonnn from Bangladesh 🇧🇩
Thank you
In which book shall I get this topic??
thank you
Hallo, can i see activation reaction for DMC? 🙏
Super❤
Thank you very much! Simply and pratically explained mam God bless you!
Use good quality mic
Super explaination better than hours of lecture u simply nailed it mam keep going good job ❤I want you to do more videos on basic chemistry
The beta-D-fructopyranose was misslabeled as fructofuranose, it‘s a 6-membered ring, not 5-membered
Youre right! I was Confused, thanks
Thank you
বাংলায় বুজালে ভালো হতো ম্যাম
Very clear and accurate 👏
Very nice explanation with authentic knowledge 🎉
in furanose the oh group on the carbon number 5 has direction to left handside not to right
Tomorrow is my exam thank you mam❤
Love you mam
Good video. I will have exams on IR spectroscopy, selection rules, on date 01/March /2024 . Can you tell me one book that I can get this full information please ? Thanks
Hello, extremely sorry for late reply... Was occupied with some family medical emergency. I find Organic Spectroscopy by Jag Mohan pretty easy for beginners. Apart from that u can also refer Organic spectroscopy” by William Kemp “Spectrometric identification of Organic compounds” by Silverstein. Also if u want to study for exams try to solve numericals based on IR on ur own by searching thru you tube or website that way u wud learn better.
I have replied from my other channel...
Great😊
I love you all
Thanks

Why do only glyceraldehyde chosen as standard molecule
Good
Improve your english You know just negligible words
I am required to find 10 types of aldohexose What are they?
That should be the aldohexoses like glucose, mannose, galactose... types as in what exactly is the question.. It should be these aldohexoses
@@chemistryscholars5060 I mean that I only know 8 of aldohexose,and l'm required to find 10.What are the other two ? Thanks ♥️
I know glucose . galactose .mannose.altrose.gulose.idose.talose .allose ......I want two more?
@@omniagg yes u are correct.. may b u can try and mention D glucose, L glucose n all .... If u start with glyceraldehyde we get these 8 forms, D and L series u can write
Thanks!!!
Nice explanation madam.... But there's no usage " called as ". It's only " called " but at the same time I say it's common mistake by us. Another is the word " spectra" doesn't change into " spectras " Spectra is the plural of the word spectrum......thank you
Thankyou... Will keep this in mind for my next videos
Thank you, a very useful video :))
Glad it was helpful!
Thank you so much for this. I have been struggling to understand this and you made it so easy for me
Glad you did... Thanku for watching
Agar jyada resonating structures hai , then that intermediate or compound is more stable. Resonating structures is one of the criteria. Secondly in this case if u have a complete benzene ring or pyridine ring, that means it has retained its aromatic character, that makes it stable as well.
Stable unsable kese identify karte he vi nahi samja
Great
Nice content it helps me to improve my notes making for exam ❤
Thanku
Very useful mam....TQ☺️
Welcome 😊
Fabulous explaination thank u very much
You are welcome

I have watched like a thousand videos online on mass spectra, but it was still a mystery to me. This one video changed everything 🙇♂️🙇♂️🙇♂️🙇♂️
Ohh thats great to know.. thanku so much
God bless your brains ma'am. You will have the highest ratings ever.
This the best video
Thankyou
