This book is a book in itself, in that for once it isn't split into sections and parts, but does basically what it says on the cover.
It looks at the theory of electron clouds and how bonds form between atoms. It goes into all the detail about orbitals and hybridisation. It looks at what happens to bonds between atoms of the same type, and between different types. It also has a quick look at what is happening in semi-conductors, which is a little bit of a detour, although there is a relationship I suppose.
The part I don't really follow is the whole bit about symmetry. I can see some of the symmetries, others are a little harder to spot. I'm not too sure why they are important though, and to what extent the rather complicated rules for classifying the different symmetries are useful.
Finally there is a case study that looks at drug design and how knowledge of the bonding sites can allow enzymes and drugs to be designed.
Chemistry seems increasingly to be a collection of complex categorisation rules and quite a bit of maths. The maths I can cope with, but there seems a lot to remember otherwise. Oh well, judging by the book count, the course is over half way through now!
