How atoms REALLY make molecules!

What is molecular orbital theory and how does it work? Are you confused about frontier orbitals, HOMO and LUMOs? These essential concepts in chemistry and science are explained with examples and 3D animations.

For a detailed academic lesson on molecular orbital theory, I recommend Chad’s Prep:

Loved your engaging presentation Dr Robertson! And already more views than mine on the topic in 6 days!!! Really well done. Thank you so much for the referral...truly a surprise!

[benjaminlum]

Yes, please cover more topics like aromaticity please! I've always had a feeling that textbooks simplify topics for introductory purposes, but I've hardly felt that way towards aromaticity until you've mentioned it, and now my interest has been piqued!

P.S. The way you cover topics are so clear and the visuals are fun :)

[nilseisen]

Definitely would watch your explanation on catalyst design! P.s your teaching rocks, leaving my curiousity vibrating

Holy moly. This is it. I’m a microbiologist and I could never understand why uni textbooks didn’t dedicate too much paper on this fundamental theory. Even the exercises where very mechanical and didn’t go beyond biatomic molecules scenarios. Of course, as a microbiologist, i’am more interested in linking chemistry theories with the unique molecular world of the cell, that is very messy.
I mean this theory it’s crazy difficult but it’s immensely powerful.
I must say that if I had you as my chemistry teacher I would be a chemist now, the energy, the passion and the amount of knowledge you put in is immensely inspiring.
Thank you so much.

Finally a good and not superficial chemistry youtube channel

[Erosis]

Would love that catalyst video! Aromaticity would be great, too. Awesome work!

Am 18 years old and Always try to find concepts on YouTube which i have difficult and finally find best video on Chemistry of bonding, orbitals ...and so on

[DwarvesAndDice]

This one video essentially summed up multiple years worth of my chemistry course... in a better, more concise and interesting way (losing essentially no detail!) Your videos are seriously amazing!

[andyburns]

I never studied chemistry beyond A Level, I like your method of explanation, we can listen to what you're saying, while allowing our brains to run ahead a little, that allows us to feel somewhat clever that we've worked out the next step, when in fact it's your very carefully laid-out path of breadcrumbs that guides us there.

A video on the catalytic mechanisms would be very interesting

[djPU]

I just want to say keep making these videos. You fill a niche on YouTube that no one else has done, you are personable and have good camerawork, you are going to explode upwards! Thanks to your passion of chemistry and education you are helping a lot of young people learn what they don’t exactly teach in school.

11:53 The reason electrons do this btw is that symmetric spins means anti symmetric wave function, which means they’ll be further apart on average. This is referring to fermi heaps/holes. The reduction in electrostatic energy far outweighs the increase in magnetostatic energy from the alignment of the electron magnetic dipoles/spins, as the electric energy drops as 1/r and the magnetic energy as 1/r^2. If the magnetic moment of electrons was much larger, that would eventually outweigh the decay rate though

I have a first class in Engineering from UCL and a PhD in physics, UMIST, and a lifetime of learning - I’m 66. Your work is incredible!

[umbraemilitos]

I would definitely like a deeper dive on aromatics, catalyst design, and other applied MO topics than some textbooks give us.

4:50 Thank you for making the point that orbitals are not containers. Too often we cause misunderstandings in our language where we say an orbital is empty, partially filled, or filled implying that it is a container into which electrons are inserted.

[notzero]

Man...this video made my day...I was struggling to understand how everything works this video covers it all...please keep up..

[davidgunther]

I've taken several years of university chemistry courses and this connected some ideas that I hadn't connected before. Thanks! A video on catalyst design and aromaticity would be great! I think they might even go together. At least when designing orbital energies the molecules usually have an aromatic part somewhere. 🤔

[RobertoHernandez-gpgu]

The 3d animations make the whole difference. This channel is gold.

[jannickharambe]

Yes, please more on aromaticity and catalysists.

[HyperactiveMelon]

Learning chemistry without any visual imagery ability sucks
