Why do certain substances react together in the way that they do? What determines the shape of molecules? And how can we predict whether a particular reaction will happen at all? Such questions lie at the heart of chemistry - the science of understanding the composition of substances, their reactions, and properties. While often fragmented into the strands of inorganic, organic and physical chemistry, a full understanding of chemistry - and establishing answers to questions such as those above - can only be gained by seeing the subject as a single, unified whole. Chemical Structure and Reactivity: an integrated approach rises to the challenge of depicting the reality of chemistry. Offering a fresh approach to undergraduate teaching, it depicts the subject as a seamless discipline, showing how inorganic, organic and physical concepts can be blended together to achieve the common goal of understanding chemical systems.
