if i didnt see this, i wouldnt be able to understand a thing about MOs bc my professor explains it like she doesn't know a thing about it as well so, thank you very much for this

[@mdshaikhsarwer4152]

Finally corrected the mistake that you did in the previous lecture in a funny and passionate way👍👍👍 I love it❤️

[@dhaneshliyanage]

There is mistake in the drawing of sigma antibonding orbital formation (30 min 20 seconds), and pi antibonding orbital formation as the phase of waves (electrons) are incorrectly represented. Same phase overlap creates construction, but different phase overlap creates destruction and leads to a node. So the diagrams signs shall be opposite in case of formation of excited orbitals. It is correctly represented in the text books energy diagram (33 min 15 seconds) as the excited pi orbital lobs with different phases are shown with different colors.

The molecular function of a cancer cell is equivalent to a formation of a brain fluid because it thinks anatishthesize it (the {cell})

[@lisa7286]

I didn't understand that last concept of switching. Can someone please help me 🥺

[@michaelgonzalez9058]

U have too watch that it expands

Remember the machine allocated to positive

U give the light of nuclear light and u have an answer

[@platones9667]

thx MIT OCW for giving us a chance to see these great professors and lectures... and make us see that our teachers suck :D

[@michaelgonzalez9058]

Like plank(h)

[@phillipsusi1791]

Wait a second, did you just show that molecular bonding theory says that dilithium should exist? Because I'm pretty sure that outside of the star trek universe, it doesn't.

[@michaelgonzalez9058]

Actually it is 10

[@michaelgonzalez9058]

There is your bonding

[@michaelgonzalez9058]

Thats why we went to hydro compulation

26:50 to 27:00 that was so funny 😂

Here we are taught this when we are 16 yrs old

[@NaN_000]

These thing are already taught in age 15 but in college they will take again so shut up

[@michaelgonzalez9058]

Use a quantum computer

[@Kyoz]

Use a Rubiks cube.

[@romanarutyunyan8709]

The most confusing lecture so far.

I didn't know how much energy spend to separate things. It's A LOT! never thought that we could using magnetic field to separate molecule It's so inspiring.

[@michaelgonzalez9058]

Like a muon of omega-minus

[@miinyoo]

I learned this stuff in high school but nowhere nearly as clearly as Jeffrey puts it. Knowing what spdf, n+l relating to harmonics and assoc'd caveats meant would have helped a lot because being given abstract looking terms without background is 1. Annoying. and 2. de-moralizing when the lack of context compounds on itself as you are described further the realities occurring with more seemingly arbitrary symbols all without the experimental evidence which demonstrates it. I didn't know those were originally spectroscopy terms with actual graphs to describe them that simply stuck when I learned about this stuff and sadly, I'll bet on this, neither did my instructor. I do now, 20 years later. It's really a pleasure to listen to Jeffrey refrain what I should have been taught more eloquently. He's not just a good instructor conveying information. He does it through storytelling which has an added benefit of entertainment value.

[@kanishk01010]

fr he is such an entertainer. i could listen to him talk about electrons and atoms all day. cant say the same for my teacher

[@shintarokohata8178]

Separation by magnetism makes a lot of sense. James C Maxwell said Electricity, Magnetism, Electromagnetism, and light are all froms of energy. Do not see why we can't separate chemicals using the polarity or chemistry atrtributes to separate the molecules. Thanks Sonya Davidson, CEO H2 Energy Now
