JEE Main Chemistry question

The acidic character of phenol (relative to a simple aliphatic alcohol) is due to

(A)Resonance delocalisation of the phenoxide ion's negative charge into the aromatic ringCorrect
(B)Tautomerism occurring in phenol
(C)Oxygen being more electronegative than hydrogen (true of all O–H bonds, including alcohols, so this alone does not explain phenol's distinctly higher acidity)
(D)None of the above

Answer: (A)

Solution

What specifically makes phenol more acidic than an ordinary alcohol is that its conjugate base, the phenoxide ion, is
