WebbThe correct option is C II > IV > III > I > V Phenols are acidic in nature due to resonance. The presence of electron withdrawing groups (such as: − N O 2, − X, − N R ⊕ 3, − C X O, − C O X, − C O O R, − C N) on the ring stabilises the phenoxide ion formed and increases the acidic nature of phenols. On the other hand, presence of an electron donating group in the ring ... WebbThe toxic compound 2, 4 − dinitrophenol has K a = 10 − 4 M. In an experiment, a buffer solution of 2, 4 − dinitrophenol was prepared with the p H adjusted to 5. Calculate the ratio of the concentrations of the dissociated ion to the undissociated acid:

WebbSolution. Verified by Toppr. Correct option is B) The electron withdrawing group (−NO 2) increases the acidity of phenols and the electron donating group (−OCH 3) decreases the acidity of phenols.
