WebFeb 20, 2024 · Phenol is acidic because of resonance stabilization of its, named as phenoxide ion. Therefore, option (A) phenoxide ion, is correct. Note: The name of the ions … WebIn the case of phenoxide, however, there are five resonance structures that disperse the negative charge over a total of four different atoms (three different carbons and the oxygen). [Pg.701] Moreover, resonance structures 1 and 5 have intact aromatic rings, whereas structures 2-4 do not. This, too, makes structures 2-4 less stable than 1 and 5.
WebWhereas in case of phenoxide ion, the negative charge on the oxygen atom get delocalize and no such charge separation take place. Therefore the resonance structures of phenoxide ion has more contributions toward the hybrid in stabilising the phenoxide ion. Hence phenoxide ion is more stable than phenol. WebCorrect option is C) Phenol is more acidic than alcohols due to stabilisation of phenoxide ion through resonance. Presence of electron withdrawing group increases the acidity of phenol by , stabilising phenoxide ion while presence of electron releasing group decreases the acidity of phenol by destabilising phenoxide ion.
