WebOct 21, 2024 · Swedish Svante Arrhenius, in 1884 proposed the concept of acid and base based on the theory of ionization. According to Arrhenius, the acids are the hydrogen-containing compounds which give H+ ions or protons on dissociation in water and bases are the hydroxide compounds which give OH− ions on dissociation in water. This concept is … WebWeak bases have strong conjugate acids. So we can identify weak bases by looking at a #"p"K_"a"# table. Caution: The #"p"K_"a"# value measures the position of an equilibrium. But leaving group ability is based on reaction rates. So although the correlation is good, it's not perfect. In general, the weaker the base, the better the leaving group.
