Electron withdrawing groups (-NO2,-CN) stabilize the phenoxide ion by dispersing the negative charge relative to phenol and increase the acidity of phenol, whereas electron donating groups (-OCH3) destabilize the phenoxide ion by intensifying the negative charge relative to phenol and tend to decrease the acid strength. Thus, the order of acidity is
