Atkins' What is Chemistry Chapter 4: Its Reactions

I love how Atkins summarized the 4 major fundamental types of chemical reactions: proton transfer, electron transfer through redox, radical reactions, and coordinate bond formation.  Profound.  Reinforced my views that chemical changes are just a series of electron rearrangement.  Organic synthesis, designing molecules is all about manipulating electron rearrangement.  Acids and bases play a role in redox because proton transfer can affect the receptiveness of electron clouds for rearrangement.
