It's fine if you are pre-med. But if you are serious about chemistry, you really will want to be at a school where there will be other students with a passion for the hard sciences. Georgetown is really an international relations/business kind of place.
Here's a listing of top graduate chemistry programs for 1993. The pecking order hasn't changed all that much, although I would probably but JHU in the high teens instead of in the forties.
