WebOct 17, 2014 · Acid-Base Reactions Of Alcohols. Alcohols are mild acids.Typical aliphatic (i.e. “alkyl”) alcohols such as ethanol, isopropanol, and t-butanol have a pK a of about 16-18, making them slightly more acidic than water. Alcohols that are in conjugation with a pi bond or aromatic ring will be more acidic since the conjugate base is resonance-stabilized.
