For example, C21H30O2, THC.

I know the basics of the Vsepr theory. Maximum "distance" away from each other (bonds), minimum repulsion.
I'm using the Vsepr, I suppose you could say.

Similar to the chart in the link. However, it doesn't deal with electron domains, it deals with # of bonds and lone pairs of electrons. If I follow this method, will it allow to build this compound properly?



My approach would be to look at each H/C/O, and determine it's shape (linear, triagonal pyramidial, etc) using each H/C/O as the central atom, and looking at the lone pairs, # of bonds, etc.

BTW, if this going to work, do double bonds count as a single bond?

are you trying to build a molecular model of this?  If so, you'll need to focus on hybrid orbitals...sp, sp², sp³...etc

Would not looking at each atom and the number of atoms connected to it, with the # of lone electrons, have the same effect, and then use a Vseper chart? Well, a chart that says something like...

Linear, 2 bonds to central atom, no lone electron pairs, 180 degrees

And obviously, comparing it with a 3D model.
