This organic chemistry video tutorial explains the difference between delocalized electrons and localized electrons. It discusses which acid is stronger - ethanol or acetic acid. it provides the pKa values for these molecules and discusses the relative strength of the conjugate base as well as the inductive electron withdrawal effect of the carbonyl group. The resonance structures of the acetate ion are drawn as well as the resonance hybrid. The negative charge on the ethoxide ion is localized making it less stable but a stronger conjugate base. Other examples include cyclohexanol and phenol in this video. This video also helps you to identify the major and the minor resonance contributor,
Delocalized vs Localized Electrons, pKa, Acidity, Conjugate Base, Resonance Hybrid and Contributors play
