Q: Comparison of C-Cl bond length in CH3Cl and CF3Cl

Topic: Chemical Bonding (Application of Bent's Rule) Bent's rule is also consistent with Gillespie's VSEPR model, and may provide alternative rationalisation for effect of electronegativity. So it is restated as: 'more electronegative atom not only prefers to stay in the orbital having more $...

Q: Chemistry Stack Exchange has a problem with unpleasant bro culture. How can this be changed?

My colleagues and I have had a few unpleasant experiences lately at Chemistry Stack Exchange. I have two colleagues who won't visit Chemistry anymore, so I asked a question myself and experienced the exact same sort of unpleasantness that they have. I have also seen many other examples that oth...

@1,3-feeds So this is about this comment?

A mere suggestion: if the simulation was done for you it doesn't hurt to ask him/her/they for further clarification. More often than not they will welcome you for putting your prepared questions on the table. — Buttonwood 10 hours ago

And also this one?

The problem is, we have no particular way to see into the mind of somebody else to determine just what they put in a table for you. Even for my own simulations, when I come back to the output some time later it can be difficult to figure out just what was put where without some really good comments. — Jon Custer 9 hours ago

I don't know what "bro" is supposed to mean; however, I don't want to know.

If such people just would use some of the energy to improve their questions instead of making long rants on meta.

There was a comment in between where the topic starter is wondering "Why are there still so many jerks like you here?" [sic]… In the absence of logic and consistency feelings start to prevail, and it simply doesn't work in field of STEM sciences which leaves people unwilling to receive any critique in frustration. And the title looks like it was written by the BuzzFeed "journalist".

what is the difference between transferable potential and potential? (context:neural networks in chemistry)

" In this paper, we demonstrate how a deep neural network (NN) trained on quantummechanical (QM) DFT calculations can learn an accurate and transferable potential for organicmolecules"

@Yashas this is possibly better suited at the main page. Don't forget to add a citation when you post it. I'm positive to find better responses there...

@Yashas in the absence of further context, I would assume that "transferable" means that it is applicable to molecules outside of the training set itself

Oh but I forgot I'm supposed to be a bro so I can't tell you that. Just pretend I said something snarky instead.

This is taking it too far...

Isn't that Bro stuff we're accused of against the new-ish CoC?

In that case, I should try it.

Q: Empirical Evidence and Assignment of Orbital Energies (Electron Filling)

I see a lot of questions on electron configurations from students at various levels here. Students mechanically remember how to fill orbitals and sorry to say many teachers do the same. Not a single general chemistry or even undergraduate physical chemistry book discusses the "why" part of orbita...

Q: Should we expect Jahn Teller distortion in bis(ethylenediamine)nickel(II)?

I got this data from an assignment problem. In the case of Copper it makes complete sense for the stability constant of formation of $\ce{[Cu(en)_3]^{2+}}$ to be that low given that we have $d^9$ configuration and strong Jahn Teller distortion leading to strain in the rings formed in the co...
