WebAlcohols are amphoteric, i.e., they can act both as an acid as well as a weak base. The acidity of an alcohol molecule is due to the presence of an H-atom bonded to the more electronegative O-atom. The basicity of alcohol is accredited to the presence of lone pairs of electrons available for donation on the O-H bonded oxygen atom.
