Advanced Chemistry

Quantum Chemistry: From Fundamental Physics to Chemical Reactivity is an open textbook that builds chemistry up from physics. It explains where each of chemistry's rules and mnemonics comes from instead of asking you to memorize them.

There are no arbitrary exceptions. There are only approximations with domains of validity.
