Molecular Orbital Diagram 2a

[ladoremimania]

oh my gosh I LOVE you :D finally understand it

[iqrasaeed93]

& If you would be able to explain how to draw it or give me a link to show it, then that would be awesome :)

[EnderlePhD]

@iqrasaeed93 Did you try your professor or any p-chem professor on your campus? 

[jdm9132girl]

OMG......Professor Enderle, you're a miracle worker! <3

[HoshiHikari]

Guess who has a final in less than 10 hours and just found this channel...

[sspena143]

You should come teach at my school, then I would know my tuition isnt completely going to waste ......GREAT video .....I can see clearly now the raiiin is gone ....=D

[anaclaudiaaa5]

you totally taught me that. thanks :)

The mixing of the 2 p orbitals already takes orbital mixing into account?

[EnderlePhD]

@danielelteso Can you elaborate a little more?

[danielelteso]

@EnderlePhD the diagram from the vid only represents orbital mixing species (N2, C2, B2, etc) but not for diatomic molecules, on which orbital mixing doesnt apply (O2,F2,Ne2). There are interactions between orbitals with the same symmery (gerade and ungerade). THe σ2s g orbital interacts with the σ 2p g and orbital mixing applies, raising the energy of the bonding σ 2p, and lowering the one form 2s. This explains it better courses.chem.psu.edu/chem210/m­ol-gallery/oxygen/oxygen.html

[EnderlePhD]

@danielelteso Yes I know. What is not clear in the video that this diagram is for N2, C2, B2, etc.? Check out the first 10 seconds. The mystery atom is N or lower in atomic number. But I see how it could be confusing if one missed that part because I don't think I repeated it again later. This video is only an example problem. Some of my other videos have the concept explained in a little more detail. I hope this explanation helps. Cheers!

[danielelteso]

@EnderlePhD oops missed that. Thanks

hello, am very very very happy to watch a video like dis

cause i study medecine in france nd our teacher explain nothinh,nothinggg. and i wasn't understand how to do an molecular orbital nd now i understand

but please i just want to ask u a question

if we are for exemple

an exercice like this

si(E3s=-13.5ev,E3p=-8.2ev) and O (E2s=-28.7ev,E2p=-13.6ev)

how do this in a molecular diagramm?

answer me fast please cause i will to pass a big big exam

thank uuuuuu

[EnderlePhD]

@musulmane191 Glad the video was helpful. In regards to your question, the energy levels for questions in these videos are estimated qualitatively based on general chemical knowledge. In your case, the energies of each level are given. I would follow the same procedure but put the energy levels on a scale.

Good luck on the exam!

[musulmane191]

@EnderlePhD

okay the exercice is

we have 2 molecules SI and O

the silicum Z=14 and the oxygéne Z=8

SI(E3s=-13.5 EV, E3p=-8.2 EV) O (E2s=-28.7 EV, E2p=-13.6 EV)

nd they say us to draw the orbital diagramm of this

[khalilmazoryar]

he is amazing prof, what uni is this?

[acmilanshevachels]

@coremaster22 and @KiyomiTakada me 3

[kingfisch99]

Thanks a lot EnderlePhD, you saved me before my midterm

[kev3000]

@coremaster22 so true

[KiyomiTakada]

@coremaster22 right...... my prof cloudn't even explain this as well as he does.
