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. The effect at p-position is greater than at m- position. WebbLook through BOC-L-2,4-DINITROPHE MSDS details show.

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 ...
