Here is what some of my colleagues recommend....
Lab1
Lab2
Lab3
They are basically the same. Some more detailed than others. Some containing weird/incorrect information. Your goal is to familiarize yourself with bonding/hybrid orbital theory/molecular geometry through hands-on model building and using an applet to virtually build the same molecules.
I am looking for
a) Molecular Formula
b) Structural Formula (when appropriate)
c) 2D Lewis Structure
d) 3D Lewis Structure (when appropriate)
e) Hybrid Orbitals used in bonding around ALL central atoms
f) Approximate bond angles around ALL central atoms
Note: Expanded octet polyatomic ions are difficult to discuss in terms of molecular geometry. Ignore them. Most of the model builders do not do well with expanded octets. I would utilize the physical models for them.
Utilize any of the model builders to the right of this post or at the following link -
