Phenoxide is stabilised by resonance effect only and it does not have any electron releasing group. So, it is more acidic than O-methyl phenol and O-methoxy phenol. But the absence of an electron-withdrawing group makes it less acidic thanO-nitrophenol. Does NO2 increase acidity? On the oth...

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...
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...
making phenol more acidic than alcohols, where such resonance stabilisation is absent. In comparison to benzene, phenol is more acidic due to the presence of the hydroxyl group. Benzene lacks an acidic hydrogen; hence, it does not exhibit acidity like phenol. The acidity of phenol is a unique...

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 ...
