Phenols turn blue litmus red i.e. phenols behave as weak acids and react with metals and alkalies as follows: Phenols do not react with Na 2 CO 3 or NaHCO 3 as they are weaker acids than carboxylic acids.. Q) Phenols are stronger acids than alcohols, why? WebJan 23, 2024 · In this case, the gas-phase results agree with the solution trend that phenol is a much stronger acid than the aliphatic alcohols, and the difference is certainly due to electronic effects. However, this commonly encountered explanation is incomplete because it ignores the role that inductive effects have on acidities of oxy-acids.
