Main Question or Discussion Point
I need to brush up on some Chemistry over Summer, and I wondered if anyone knew of some problem books pitched at a similar level to Irodov's problem book for Physics, or things like IChO questions. Preferably it would include all of physical, inorganic and organic, to some degree. I get various hits on google (like this one) but it's hard to tell what's good and what's not, so I thought I'd ask here! Thanks.
