[@peternashaat4131]

it might be the best channel ever you can find in RUclips explaining organic chemistry in a beautiful delicate way

[@kirtichuchra1339]

i must say @knowbee this is wonderful thing that you people are doing to teach all basic things despite being busy in your lives , I appreciate your start up and will continue to learn :)

[@fauntleroycliftonguitar5489]

I'm so glad you posted again. Your explanations are the best!

[@Knowbee]

So glad i could help you. Thank you for your kind words.

[@alexafromamazon6597]

Thank you! This was incredibly informative. I have to present a paper written by my professor and this made interpreting the UV-VIS data more understandable.

[@dungdavid380]

I love way you explain the problem, it is extremely clever that help understand knowledge faster. Thank you very much!

[@lubnawahab]

Sir plz keep doing the great job u do.. I don't know what are the last three vdos u posted... But ur chemistry is best the way u teach is remakable... Truly a gem..

[@sunilmarathe889]

certainly the best channel for organic chemistry

[@shbiotechnology]

Greetings!
Clear crisp explanation.
On principle of UV spectrometer.

[@Amelia-om7ew]

No one:
Knowbee: Here's some vocab
lol jk this vid was extremely helpful, thank you so much

[@monke112]

Thanks a lot for your lectures. These are very easy to understand.

[@Syllonay]

You explain it so well, thank you !

[@khizarhayat1387]

This chanel is one of the best in youtube

[@nishaminirathnayake288]

Thanks a lot .Gained so much from your channel.

[@radhaagrawal3110]

Plz make some more videos on UV . Your videos are wonderful sir

[@mustafakhan6701]

sir much much informative video thanks for uploading and make more videos for viewers.

[@noreedtechno6733]

Plz upload videos on physics too. Your videos are really good . After watching them everything gets clear. 😊

[@jdcl3446]

Fantastic video, thank you very much!

[@yoga9455]

What a clarity!!!!

[@jagannathsahu1889]

Beautifully explanation 🤗

[@curtpiazza1688]

Powerful presentation.....thanx!

[@Iamdebeshbairagi]

Best explanation

[@Supdada]

Sir will u do video on mossbaeur Spectroscopy and ESR?

[@seemanaeem8787]

love your channel. Thanks for saving me.

[@emillymasika]

Thank you so much for this elaborate and precise presentation. Am grateful 🙏

[@mr.mscnutrition]

Amazing Explaination sir👍🤩

[@pharmasolutionpakistan7668]

Ur explanation are good

[@beeravelliravikumar]

Great lecture

[@nok101fc]

Thanks. This video is very helpful to me.

[@Knowbee]

Glad it helped!

[@Warschibarschi]

Great! Thanks!

[@muhammadijaz6676]

Upload lectures for inorganic chemistry

[@ryanahmed3892]

How the path length is directly proportional to the absorbence??

[@veeru_sagar2471]

It was already there... But anyway one of the best channel I found in RUclips

[@Knowbee]

Wow. Thank you very much for saying so. A very flattering comment. Hope the videos help.

[@veeru_sagar2471]

I copied all ur words to teach my students

[@Knowbee]

That's awesome. I'm glad you were able to help others!

[@toobaalam2830]

Very nice

[@techtimes1985]

Wow excellent lecture, I'm sharing with my students.... Btw how did you make this video, software etc?

[@paramanandsingh7346]

Sir please upload the mass spectrà related problems which come in csir

[@mysteryinchemistry5488]

If atomic orbitals are overlapping laterally then how can you say it as a sigma bonding MO. It should be pi Mo.

[@DD31888]

Got solution to your question ??? I too HV this doubt

[@mahmoudtony6905]

Hope you return back to online lectures

[@vegotiharshika]

Nice explanation

[@fidato795]

God level❤

[@alirazaaliraza8113]

Sir please help me why benzene show three band in UV visible spectroscopy

[@yasirnawaz2927]

Thank you very much sir

[@muhammadishaq6647]

Sir, please upload further lectures about uv.

[@paulabukhalil3880]

One correction: It's all pi-bonding. The pi-system (the double bond(s)) is made up of unhybridized p-orbitals. The unhybridized p-orbitals aren't sigma-bonding. Even your figures show pi-bonds - the vertical arrangement of orbitals side-by-side.

[@fattila62]

Exatly

[@AbdulSamad-sx2pd]

Great

[@ilsal4853]

Why you are not uploading any videos about last 4 years ? What happened?

[@TamilTamil-so2ws]

Very nice

[@kondwanimwafulilwa5521]

Well understood

[@mikepatnode4407]

😊thank yoooou!❤

[@arupjyotisaikia7749]

Thanks

[@geoseries]

Sir Can You Provide Them in PDF format or in PPT.

[@AmazingLife1482]

Nice

[@melissajules9670]

the best

[@rassimsimou1594]

Good

[@ishfaqwani9216]

Sir upload esr and mossbaeur spectroscopy

[@ImtiazAhmed-re8ng]

Come back, teach again

[@abdullahsheikh7588]

Why there is no Arabic translationp?

[@rubenmontes_]

I think I watched this vid during Organic chem, now I'm re watching it for physical biochem lol

[@Vin_-wg8oy]

you sound like Randall Park.. Louis from Fresh off the Boat

[@plamenpenchev262]

6:34 all four orbitals are pi orbitals. Sigma and sigma antibonding orbitals chacterize another bond between carbons and they both have axis of symmetry that is why the are called "sigma".
It is interesting (but rarely done) to regard the symmetry according inversion center if this is S-trans 1,3-butadiene. Then you can illustrate the allowed (between g and u and vise versa) and forbidden (g -> g and u -> u transitions. u = ungerade, g = gerade). I do it for my students.

[@cricketjones]

if you click link it goes to spam

[@Knowbee]

I updated the description. You can now contact me.

[@mohsenshayan9798]

If you are showing molecular orbitals made from side by side overlap of p atomic orbitals, then all the resulted molecular orbitals should be called pi. There shouldn't be any sigma and sigma star in the diagram. This video is graeat, the only mistake is the one that I and others have mentioned in the comments, so please reupload the video.

in 1 trillion years the universe will freeze and this will show up

[@ireneortegaalvarez6043]

very long and he doesn's say new

[@waleedkhan-nc8en]

Best explanation

[@swag_designs5470]

Thanks
