The constant changes … WitrynaAns: The greater acidity of the –OH hydrogen in acetic acid is due primarily to two factors: resonance and inductive effects. In acetic acid, the presence of the neighboring carbonyl group has an electron-withdrawing inductive effect on the –OH hydrogen, increasing its acidity relative to ethanol, in which there is no carbonyl group. lalandia billund kartaWitryna9 lut 2024 · The correct order of pKa values for the following compounds is. ...
