<Organic chemistry> studies carbon-based molecular structures and their transformations, with emphasis on connectivity, functional groups, and stereochemistry. Carbon's ability to form chains, rings, and multiple bonds supports a very large range of molecular architectures.

A reaction can change one functional group while preserving the rest of a framework, or form a new carbon-carbon bond that enlarges it. Following electron movement and testing competing mechanisms makes these transformations predictable rather than a catalogue of isolated recipes.
