The 18 Electron Rule for Transition Metal Complexes

[@shepshep8654]

I just want to let you know you're a personal hero to me. Thanks for the lessons.

[@nirnama.aksara]

This lesson is enlightening my insight

[@Ensaima]

i should see your chemistry playlist. Becouse i dont understand 60% of your funny words

[@David-pp9jw]

We love you Dave-keep up the work!! ⭐

If you count ionically, as you have done in the video, then for carbenes one needs to a priori know if it is Fischer or Schrock type to either treat it as a neutral 2 electron donor (the carbene), or a dianionic 4 electron donor in the case of a Schrock type system. Take (CO)5Cr=CR2 as a prototypical Fischer carbene: anionic counting (which in this example is identical to covalent counting) means that the count would be 5 x 2 (CO) + 6 (Cr) + 2 = 18 VE, but that is only because I know it is Fischer type, and hence the carbene is neutral 2 electron donor. If I treat it as Schrock type, then the CR2 fragment is 4 electrons 2- charge: 5 x 2 (CO) = 10 + Cr(2+) = 4 + 4 (CR2) = 18 VE (as in your table). But this is incorrect, since the Cr is in the zero oxidation state for Fischer systems... We get the same number, but the assignment of Cr(2+) in the ionic counting scheme is incorrect. So a better approach is covalent counting across the board, as one need not know a priori the charge assignment of a ligand. Same goes for carbyne counting (or alkylidyne).

I like your funny words magic man

All I know is that methamphetamine is an organic compound🥲🥲🥲

awesome, new chemistry video!

[@vedvod]

Well explained 🎉

Thank you for not shying away from the heights of your intelligence! Keep doing this type of science when you're not debunking pseudoscience!

[@turdferguson3400]

Question: why is the alkyne restricted to donating only 2 or 4 electrons? Why not 3 since it has a triple bond?

[@Valdagast]

Does this become a 32-electron rule for the actinides and lantanides?

[@sanskarkosare1653]

Thank you sir ❤

[@harshitalalwani8127]

Thank you it was helpful!

[@josipbroztito4840]

Pleasee make video about isolobal analogy

[@psyseraphim]

Hey Dave, love your content. Just dropping by to ask if maybe, just maybe, we could see a future collaboration between you and Forrest Valkai who does a lot of Tik Tok stuff and appears on Atheist Experience. It seems that neither of you do many (if any) collaborations but your style and inflection are so similar I feel like it might be a really great fit and could produce some epic, informative and entertaining content. Anyway keep doing what you're doing, much love.

[@eatshitlarrypage.3319]

I would second this. Forrest Valkai is a precious, precious cinnamon bun who truly has a love for science communication.

[@DILSHANYOOSUFCHEMISTRY]

Can you please explain how η5-C5H5 contributes 6 electrons to a complex ?

[@ProfessorDaveExplains]

Don’t forget the negative charge.

[@qwerteria7366]

Bond with me Electron-sama

[@CM-ng1ef]

great video

[@jackknife4547]

But can a TV BE flat?

[@jackknife4547]

I remember when TVs had a curve😆

[@JamesD2957]

How do you figure out the carbonyl groups are neutral?

[@troy6882]

It's such a shame I'am still studying but the anti is going to be fun hear and ever think at a pole N/S that there's the hole bend at that very centre between magnetic field lines the iron used as the bond or fabric hole mechanics!.😃😄😁😆😅 5 Smile's

[@eldersprig]

so if an electron falls on the floor, if i get to it in 18...uh never mind

[@mallelaxmikanth2875]

the interest to learn a new topic is completely dead after watching this video.

[@waelfadlallah8939]

God i love this topic

[@hinashahzadi5933]

Cp always contribute 5 e not 6 as you are telling??

[@carissalloyd4305]

Depends whether you're using the ionic or neutral counting method. In the ionic method, Cp counts as 6 whereas in the neutral method it counts as 5.

Why are there no comments lol (i was 2nd)
