I know what you mean about the semester final exams. Bleh. I have my AP Chem final tomorrow, as well as Weight Training (meaning I show up and get an A ). By the way, if you have the chance to take AP Chem, thinking it will help with the web shooter, don't. It hasn't helped so far, I don't think it will except a little bit with an organic unit at the end.

How polymers are drawn? Depends on if you have ions in your formula, how many monomers you have, if it is going to be considered organic, if any of the elements used can be hypervalent, etc. If you have ions, just make sure to put the appropriate amount of electrons on the central atom in the covalent bond. And remember, monomers can bond separately if their effective nuclear charge is not balanced (all 0s) per bond site atom. Organics, nothing special really with those... just a lot of carbon bonding to stuff, but carbon can bond in a hexagonal or pentagonal pattern. Look up the Lewis structure for caffeine, you'll see what I mean. And remember, atoms can be hypervalent if they are in group 3 or later of the periodic table.
