WebApr 15, 2024 · The degradation of phenol at different concentrations by three strains was investigated at low temperature [Fig. 1 (b)]. At the degradation of 100 mg L −1 phenol, the degradation rate of Ju-A4 was 100% in 20 h, with a maximum degradation rate of 8.53 mg h −1. The degradation rates of Ju-A1 and Ju-A6 were 48.5% and 42.4% at 20 h. WebNitro groups have a large acid-strengthening effect on phenols. The pKa of 4-nitrophenol is 7.15, whereas that of phenol is 9.89, a factor of almost 1000. Account for the greater acidity of 4-nitrophenol relative to phenol on the basis of resonance and inductive effects. WebIn chemistry, the mesomeric effect (or resonance effect) is a property of substituents or functional groups in a chemical compound.It is defined as the polarity produced in the molecule by the interaction of two pi bonds or between a pi bond and lone pair of electrons present on an adjacent atom.

WebInductive and mesomeric effects in electronic density distribution are well known from the aromatic substitution reaction mechanism. A substitute with a free orbital is able to increase the electronic density in the ortho and para positions, which leads to a shielding of the corresponding carbon and hydrogen atoms resulting in an upfield shift. . Especially in … WebJul 19, 2024 · Substituents on the phenol ring can have a significant effect on the acidity of phenol . For instance, electron withdrawing groups (EWG) increase the acidity of phenol. EWG stabilize the phenoxide ion further by inductive and resonance effects. On the other hand, electron donating groups (EDG) decrease the acidity of phenol.
