Questions and Answers

What is the main reason phenols are slightly acidic in water?

As a result of the resonance stabilization of the phenoxide ion (correct)

Because of the hydroxyl group's ability to donate a proton

Due to the electron-withdrawing effect of the aromatic ring

Due to the presence of a benzenediol functional group

Which of the following is NOT a characteristic of phenols?

They are white solids that are easily oxidized by atmospheric air

They are highly electrophilic and readily undergo nitration

They are hygroscopic and soluble in water

They are non-polar and insoluble in water (correct)

What is the product of the reaction between a phenol and aqueous sodium hydroxide?

ArONa(s) + H2O

ArONa(aq) + H2O (correct)

ArOH(aq) + NaOH(aq)

ArOH(aq) + NaOH(aq) → ArONa(s) + H2O
