The conjugate base of hydroquinone is used in the synthesis of PEEK. Is hydroxide a strong enough base for deprotonating hydroquinone? Phenolic protons (pKa ~ 10) are acidic than water (pKa ~ 15.7), therefore the equilibrium favor deprotonation of hydroquinone by hydroxide.

Explanation:

Equilibrium always favor the formation of weak conjugate bases and acids.H20 (pKa ~ 15.7) is a weak acid than phenol (pKa ~ 10) and thus the equilibrium will favor the deprotonation.[pKa ∝ 1/Acidity]Answers: Phenolic protons are more acidic than water,therefore the equilibrium should favor deprotonation of hydroquinone by hydroxide.
