Examples of s-p Mixing in Molecular Orbital Theory

Admittedly, my prior tutorial on MO theory was a little confusing, and had some errors. I wanted to make things right, so here's another one! This will clarify some of the basic concepts, and will also extend them to discuss a new concept, s-p mixing. Let's dive right in!

Check out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!

WOW! What a change, almost fell off my chair when he said it was professor Dave!!! I like the change!!

[VyvienneEaux]

Professor Dave, I don't know how to thank you enough! I'm in an advanced physical organic chemistry class right now, and we're learning qualitative molecular orbital theory. This video is going to be an incredible asset!! Would you consider making any more videos on this topic?

[sophieshepherd]

Thank you so much! I've spent hours going over the textbook and you've explained it better in 10 minutes than all of that reading.

[sarahholland]

thank you sm! starting organic now and completely forgot what the molecular orbital theory was since it's been nearly a year since I took genchem. this video was comprehensive enough that most of it came flooding back. much thanks!

[realest_isopod]

Currently taking bioinorganic chemistry and needed to brush up on my MO knowledge from gen chem, this was an excellent review! Many thanks

[calistawithay]

Woah woah- when did Professor Dave get a hair cut??

[thatsnotme]

Definitely needed this in December! It's great that you're continuing the rest of the theory

[joshuamcdonald]

As usual great stuff, I really hope you know how great your content is! Really explains things clearly and succinctly.

Thanq dave, i searched for this concept for 3 years, but in this video i have gained full clarity

[andrebarros]

I'm studying in Italy. My Italian professors make everything sound so difficult. You make everything sound so easy! 😍❤

[fellowearthling]

Just today I was thinking about how I need to watch more videos on MO theory bc I'm having trouble visualizing certain things, and I was roaming around on your channel when I saw this video had coincidentally just been posted!


Nice

[bimanh.saikia]

Looking good in short hair.. As well appreciate your work.... Regards from India...

[suyashsingh]

Well explained professor!
Regards from, India🇮🇳

[sofdia]

The haircut caught me off guard... but it looks good! Appreciate your videos

[akeel_hussain]

Thanks a lot...your lectures had gave me too much knowledge - concepts and skills to learn all about Chemistry especially Organic Chemistry...
I have a request, please make a big playlist of Amazing problems that came (or likely to come) in Competitive Exams (like JEE ADVANCED in India and all other exams)

[ankitsehgal]

Sir I was in doubt since last 2 years about reason of s-p mixing.. Finally I got my answer.. Thnku so much..
Befor that, I saw many videos, books but never get satisfied answer about s-p mixing

At 8:08 don't all the orbital energies decrease from left to right? I don't understand this explanation.

[ardvark]

Very nice, but it does not quite explain the origin of why sp mixing actually occurs. Yes indeed, the symmetry of mixing orbitals needs to be correct and yes, the energy difference of mixing orbitals may not be too large. This is however not enough to explain why it happens. A more complete reasoning is based on thermodynamic considerations causing the molecule to strive to lowest total electronic energy when its molecular orbitals are filled with electrons. If a lower total energy can be achieved by sp mixing as compared to a situation without such mixing, then mixing will occur. Of course such only with orbitals of the correct symmetry and comparable energy as explained in the video.

[balwanjadhav]

How the electron overlap constructively and ditructively at the same time to form bonding and antibonding orbitals

[chanteswonderland]

still wondering i see sigma p and p* all going down in energy as Z increase, so which part did i misunderstood when mentioned they going up energy? i see the trend they are going down but the delta E is increase, does that part u mentioned the E gap or just simply the orbital energy level for sigma p n p* 🤔🤔🤔😣😣? thanks for clarification,

and do we have heteronuclear diatomic molecular for CO and NO or CN - so on as well 🤔🤔🤔👍👍👍thank u again for making science easier for the world
