Chapter 10 ?2010, Prentice Hall Organic Chemistry, 7th Edition L. G. Wade, Jr. Structure and Synthesis of Alcohols Chapter 10 * Structure of Water and Methanol Oxygen is sp3 hybridized and tetrahedral. The H?O?H angle in water is 104.5?. The C?O?H angle in methyl alcohol is 108.9?. Chapter 10 Chapter 10 * Classification of Alcohols Primary: carbon with ?OH is bonded to one other carbon. Secondary: carbon with ?OH is bonded to two other carbons. Tertiary: carbon with ?OH is bonded to three other carbons. Aromatic (phenol): ?OH is bonded to a benzene ring.
