22.1 Nomenclature Nomenclature • The C-OH is the 1 carbon for numbering and is implied • Substituents are cited in alphabetical order and are numbered to give the lowest numbers possible • However the hydroxy substituent has lower priority than acyl and carboxyl groups 1 22.2 Structure and Bonding Structure of Phenol • Phenol is planar with resonance delocalization of the phenol nonbonding electron pair into the ring 2 22.3 Physical Properties Physical Propertie
