Protonated imine pka
WebbpKa = – logKa The p K a is the quantitative indicator of the acid strength. For our two compounds, we have pKa1 = – log10-16 = 16 < pKa2 = – log10-38 = 38 pKa (EtOH) = 16, pKa (EtNH2) = 38 What we notice is that the alcohol is a stronger acid but has a lower pKa value and this is true for any molecule. Just memorize this!
