I am confused on basic vs. molecular geometry. If molecular geometry only focuses on the atoms (not the electrons) why do the dash-wedge drawings include electrons (ie. trigonal pyramidal instead of tetrahedral)? Shouldn't this be the other way around (including electrons in drawings show electron repulsion effects)? I am looking at p. 117, section 2.5 (Molecular geometries and VSEPR Theory) of the 2020 classroom companion

Hey Kayleen, thanks for being super specific about what you were looking at, it was really helpful!

Yes, molecular geometry focuses on the atoms. I think that the diagram here just has the electrons on wedge/dash to remind us of the fact that these electrons are still taking up space around the central atom in a similar fashion which would give rise to our trigonal pyramidal vs. bent configurations we see.

I hope that that explains it. Let me know if you have any further questions.

Happy studying,

Molly
