Which atom goes in the middle of a lewis dot structure?

I've read online in multiple sites that the least electronegative atom goes in the middle with the exception of H, which always goes on the outside. However, in the molecule NaCN, C is in the middle. ...

relativistic effect: d-electrons in metallorganic complexes

With higher period the d-electrons of the metal are less strong bonded and therefore oxidative addition is easier for $\ce{Ir(I)}$ as for $\ce{Rh(I)}$ and much easier as for $\ce{Co(I)}$. For metal ...

Why fluorine doesn't act as the central atom in inter-halogen compounds?

Why can't fluorine be the central atom in inter-halogen compounds? A $\ce{F-F}$ bond is weaker than a $\ce{F-X}$ bond and thus, fluorine should be happy to form inter-halogen compounds. But, why ...

Why does Oxygen not like to be doubly Anionized?

The Electron Affinity of a neutral Oxygen atom is -142 KJ (it releases this energy). The Electron Affinity for the now anionized Oxygen is 710 KJ (Work must be done on the atom). My question is, why ...

Are there any major exceptions when comparing electron affinity?

I was tasked with figuring out whether Carbon or Nitrogen has a more negative electron affinity value. I initially picked Nitrogen, just because Nitrogen has a higher Z$_{eff}$, creating a larger ...
