WebNov 22, 2024 · Phenoxide ion shows one resonance form less making it less stable. Also it has no group which will inductively pull away the negative charge (which NO2 does very well), therefore we can conclude that 4-nitrophenol will in fact be the the stronger acid and protonate phenol. pKa (4-nitrophenol) = 7,15 pKa (phenol) = 9,95 Share Improve this … WebApr 6, 2016 · Phenoxide is a conjugate base, which means it is formed from an acid that has given up its hydrogen.
