Why do compounds like $\ce{SF6}$ and $\ce{SF4}$ exist but $\ce{SH6}$ and $\ce{SH4}$ don't?
Both $\ce{SF6}$ and $\ce{SH6}$ and $\ce{SF4}$ and $\ce{SH4}$ have the same central atom and the same hybridization but my teacher specifically mentioned that $\ce{SH6}$ and $\ce{SH4}$ don't exist. ...

How do I figure out the hybridization of a particular atom in a molecule?
I'm learning how to apply the VSEPR theory to Lewis structures and in my homework I'm being asked to provide the hybridization of the central atom in each Lewis structure I've drawn.
I've drawn out ...

Why is this atom SP2 hybridised?
I'm doing exercises on hybridisation, and I was given this molecule (this is the facit):
I'm wondering about this (electron deficient) oxygen atom. My intuition says it should be ${sp^2}$ like the ...

Resonance structure and hybridisation
I was given the first structure, and then drew the other 5 resonance structures.
First of all, are they correct? ChemBioDraw had some complaints, but as far as I can see there's the same amount of ...

Hybridization sp3 and sp2
When we calculate the electrons and orbital numbers in $\ce{CH4}$ $sp^3$ hybridization we have taken 3 electrons from $2p$ of $\ce{C}$ and 1 electron from $2s$ of $\ce{C}$ but in $\ce{C2H4}$ we have ...

What is natural bond orbital theory used for?
My understanding is that the NBO methodology transforms the molecular orbital picture of a molecule into a collection of pairwise interactions (bond orbitals). This is obviously handy for didactic and ...

Non-integer hybridization
I've known that hybridization in distorted geometries is not exactly $sp^3$ or $sp^2$ or whatever. For example, $\ce{PH3}$ has nearly pure $p$ orbitals in the $\ce{P-H}$ bond, and the lone pair is in ...

What makes banana bonds possible in diborane?
Diborane has the interesting property of having two 3-centered bonds that are each held together by only 2 electrons (see the diagram below, from Wikipedia). These are known as "banana bonds."
I'm ...

Color of chromate and permanganate
I've heard quite a few times that the chromate and permanganate have a $d^3s$ configuration. Also, their colors arise due to a rapid switching of electrons between the oxygen and metal atoms.
I don't ...
