Chemistry of Carbon Compounds

Rodd (Editor), Chemistry of Carbon Compounds, Five Volumes, each in two parts, 1951- (Elsevier Press Cleaver-Hume Press). 

One of the cornerstones of the chemistry of carbon compounds (organic chemistry) is Kekule s concept, proposed in 1858, of the tetra-valence of carbon. It was independently proposed in the same year by Couper who, however, got little recognition (vide infra). Kekule realized that carbon can bind at the same time to not more than four other atoms or groups. It can, however, at the same time use one or more of its valences to form bonds to another carbon atom. In this way carbon can form chains or rings, as well as multiple-bonded compounds.
