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. WebDec 2, 2014 · A lot of people rationalize the acidity of phenol by saying that resonance is responsible for much of phenol's acidity as opposed to aliphatic alcohols. However, this image suggests that in fact the inductive effect is responsible for a great deal of phenol's …
WebThe -OH group in phenol exhibits a +M effect due to the delocalization of the lone pair on the oxygen atom towards the ring. As a result, the electron density on benzene rings increases, especially in the ortho and para positions. As a result, phenol is more prone to electrophilic substitution reactions. WebApr 13, 2024 · o-Cresol shows high toxicity and stability. To explore a better degradation method of o-cresol, the degradation of o-cresol by three kinds of microalgae (Selenastrum capricornutum, Scenedesmus obliquus, and Microcystis aeruginosa) was researched in this paper. The growth status and degradation rate were used to reflect the tolerance and …
WebDec 15, 2024 · The inductive effect is the charge dispersal effect of electronegative atoms through σ bonds. The inductive effect is addictive; more chlorine atoms have an overall … WebBecause the inductive effect depends on electronegativity, fluorine substituents have a more pronounced pKa-lowered effect than chlorine substituents. In addition, the inductive takes …
WebApr 9, 2024 · Phenol is less acidic as compared to the above two because no electron withdrawing group is present and there is no inductive or resonance effect. Methyl phenol shows the electron donating inductive effect, hence it is least acidic among the following. So, the correct answer is “Option A”.
