This topic is not easy to understand but this vdo helped a lot ... Instead it cleared this topoc completely for me... I wish. Aap ese hi or vdos bnaenge pther topics pr bhi... Thankssss alot
thanks so much you very very good teacher al all could you explain the homo and lumo for porphyrin and Pc with metal and witout please as soon as possible
First of all ty for giving us this very very helpful kind of videos.. nd sir i m in m.sc chemistry nd sir mera frnd h apke group m mene dkha h notes pdfs mil jaati apke group m so sir its a request ki ap add kr lijiye plzz sir..
See, in case of butadiene you have total 4 pi electrons (2 double bonds), and there are four Molecular orbitals formed, one atomic orbital like atomic orbital can occupy only 2 electrons, thus first MO will get 2 electrons and it is occupied, second orbital will also get 2 electrons thus it is also occupied, now for remaining two molecular orbitals you don't have electrons thus third and fourth Molecular orbitals are unoccupied.
Basically it is quantum mechanical calculation, but without using calculations, count the number of nodes, higher the number of nodes higher is the energy....
Yes, it is a part of Pericyclic reaction and Pericyclic reactions are there in the syllabus. One more thing, also check my video on pi Molecular orbitals of Benzene, a question was there in June 2019 CSIR NET exam from pi molecular orbitals of Benzene.
Your lecture is the only one i found on this topic that actually makes some sense. Good work!
Thank you, now i can watch "big bang theory" and fully understand what sheldon is talking about
very lucid qualitative explanation sir, thank you very much.

fabulous explanation, you made it so easy sir. Thank you very much.
Clear cut concept sir. I understood very well.
That is fantastic Sir.
Very very very very well explained ....
Thank you very much, please watch other lectures also and share with your friends and students.🙏🙏🙏
Thankyou sooo much sir.....😇 please make more such videos, your explaination is really very good.....
superb explanation sir, thank you very much
Thank you very much

Will try to upload.

Sir i am clear now completely🤗🤗🤗🤗🤗
Thanks sir... This video is very helpful... Plz sir homo lumo of acetone ka bhi video banao sir..
Ok will try when time permits
Sir orbitals are not visible clearly...next time use colour markers... Explained well...excellent
Yes I have changed the method now
Thank you so much for this kindness sir
Sir exact and bta den plz plz plz plz why benzene show three band at different wavelengths i.e at184 ,204,254
Plz sir
When benzene show absorbance band at 184
Why benzene show absorbance band at 204nm
Why benzene show absorbance band at 254nm??
Sir, how can we understand whether they are occupied or unoccupied
See, in case of butadiene you have total 4 pi electrons (2 double bonds), and there are four Molecular orbitals formed, one atomic orbital like atomic orbital can occupy only 2 electrons, thus first MO will get 2 electrons and it is occupied, second orbital will also get 2 electrons thus it is also occupied, now for remaining two molecular orbitals you don't have electrons thus third and fourth Molecular orbitals are unoccupied.
How we can determine the lowest energy and highest energy orbital..on what basis
Basically it is quantum mechanical calculation, but without using calculations, count the number of nodes, higher the number of nodes higher is the energy....
Thank-you sir ji
Sir can u please make videos on microscopic techniques?
Please specify which aspect of microscopy you need, I will try to make a video on that...
@@TETRAHEDRONCHEMISTRYCLASSES atomic force microscopy (AFM)
Ok I will try in the future days
@@TETRAHEDRONCHEMISTRYCLASSES thnk you sir
Treat it Quantum mechanically and prove that for 2n carbon atoms the longest π->π* transition for Linear polyenes is given by -4Beta Sinπ/2(2N+1)
Sir, is this topic in GATE CSE syllabus also?
Yes, it is a part of Pericyclic reaction and Pericyclic reactions are there in the syllabus. One more thing, also check my video on pi Molecular orbitals of Benzene, a question was there in June 2019 CSIR NET exam from pi molecular orbitals of Benzene.
Thanks sir😊😊
TQ u Sir .
Thanks a lot Sir
Your welcome Dhapu ji
जै गुरु श्री श्री ठाकुर अनुकूलचंद्र चक्रबर्ती।
Very greatful to you
Thank you very much
Thank u
Sir video bna den ya beset hi btana den likh kr please bta dijia ga pls
please explain mass spectroscopy
Usha C will try for mass spectrometry in the future
Uploaded Mass Spectrometry Basics
Plzzz video on i r
Yes very soon, I will upload IR Spectroscopy.
Voice bohot kam hai
Yes that was without Mic, plz adjust...
Thank you sir
Please follow the lectures..
This video picture quality is very bad
Yes that was an early video of my channel.... Sorry for inconvenience caused
Thanks sir🤗🤗
Thank you sir
