linear versus angular
How would you distinguish whether a molecule is linear or bent? Does it have to do with lone pairs or polarizability or something else? I am just a little confused on how you figure out the shape.

Re: linear versus angular
To figure out the geometry of the molecule, you have to determine how many lone pairs are existing (if there is any) to help you identify what type of geometry the molecule has.

Re: linear versus angular
When describing molecular geometry, lone pairs and bonds are included in the description. When describing shape of a molecule, only bonds are taken into account. Thus, lone pairs and bonds within the molecule are responsible for determining whether a molecule is linear or bent.

Re: linear versus angular
A compound seems to be bent when there is a lone pair on the central atom because the lone pair repulse the bonding pairs and sightly displace them.

Yes, it has to do with lone pairs and polarity, so if these charges are present they will repel other elements and cause the bent shape that is observed in water rather than the linear shape present in co2 when there are 2 lone pairs that repel the other elements equally.

I'm not quite sure that the charges from polarity has anything to do with it. A molecule can be polar as a result of its shape (because its dipole moments don't cancel) but whether a molecule is polar or not doesn't influence the shape.
