Para-nitrophenol is more acidic than phenoldue to the presence of an electron withdrawing group, -NO2group, which enhances the acidic strength of the compound by stabilizing the phenoxide ion and the ortho- and para-positions in the benzene ring becomes electron rich. Which is more acidic c6h...

to cumene hydroperoxide.When cumene hydroperoxide is treated withdilute sulfuric acid,it rearranges and splits into phenol and acetone. Because the reactants areinexpensive and the process is simple,the acidic oxidation of cumene is used to produce morethan 95% of the world’s supply of phenol...
Why is p-nitrophenol a stronger acid than phenol itself? Hypochlorous acid is a weaker acid than chlorous acid. Draw electron-dot structures for both and explain why. For p-nitrobenzoic acid and p-methoxybenzoic acid which is more acidic? Explain this reactivity difference...
Usually the complex of the ionic species is much less stable than that of the un-ionized one, the hydrophobic cyclodextrin cavity favouring uncharged molecules.2-6 In the case of p-nitrophenol, however, the shift in pK, is of opposite sign;2 the formation constant of the complex of p-...
b) The pKa of p-nitrophenol is lower than the pKa of m-nitrophenol (7.2 vs. 8.3). Acidic Strength: The strength of an acidic substance can be determined with the help of the pKa values of the substa...

The surface of sea urchin-like NiCo2O4 is positively charged within acidic solutions, which effectively attracts HSO5− near the material to generate more SO4•− [37]. However, HSO5− cannot be stabilized in alkaline environments and reacts as shown in Equation (1), resulting in a ...
