Molecular Geometry of H2S

[Muggs]

According to Chad's GC handout on this a molecule with 5 electron domains, 3 of them being non-bonding pairs of e-s results in a "linear" molecular geometry. Is this a mistake? Destroyer says that H2S (which would have 5 e- domains and 3 nonbonding pairs of e-s) has a "bent" molecular geometry.

I thought it was bent as well, since Sulfur and Oxygen have the same valence. It should resemble water. I think destroyer is right.

Destroyer is right. "Shape is a family trait" like with people haha. S and O are in the same family. So they would both be bent. Another example is say CH4 and SiH4 would have the same shape since C and Si are in the same family.

Chad is actually correct. A molecule with 5 electron domains plus 3 non-bonding electrons have linear molecular geometry.

H2S has FOUR electron domain. And with 2 non-bonding electron pairs, its molecular geometry would be bent.
