WebJun 20, 2016 · para -Nitrophenol phenoxide ion is stabilised by -R and -I effect where both -I and -R effect are minimum. Thus according to stability of anions o -derivative will be more acidic than p -derivative which will be more acidic than m -derivative. 4-Nitrophenol can be used as a pH indicator. A solution of 4-nitrophenol appears colorless below pH 5.4 and yellow above pH 7.5. This color-changing property makes this compound useful as a pH indicator. The yellow color of the 4-nitrophenolate form (or 4-nitrophenoxide) is due to a maximum of absorbance at 405 nm (ε = 18.3 to 18.4 mM cm in strong alkali). In contrast, 4-nitrophenol has a weak absorbance at 405 nm (ε = 0.2 mM cm ).
