In general we will find that the acidity of alcohols is determined by the energy of the There are three main kinds of substituent effects, inductive effect substituents, alkyl A complicating factor in Bronsted acidity is that because liberation of a proton Electron donating substituents decrease the Bronsted acidity of phenols:
