WebJan 19, 2024 · What is the inductive effect of phenol? Electron-withdrawing substituents make a phenol more acidic by stabilizing the phenoxide ion through delocalization of the negative charge and through inductive effects. The effect of multiple substituents on phenol acidity is additive. Does benzene have inductive effect? 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”.
WebMar 12, 2024 · In order to study the increasing or decreasing effects of substituents on antioxidant activity, we designed all of our target compounds to have one common phenol ring with an o-OCH 3 group (Y in Fig. 1), which will provide a baseline antioxidant activity based on the DPPH assay.The reference compound has a common phenol ring (Y) … WebElectron-withdrawing substituents make a phenol more acidic by stabilizing the phenoxide ion through delocalization of the negative charge and through inductive effects.
