Arrange Bases In Decreasing Order Of Extent Of Their Ionization At Equilibrium

Arrange the bases in decreasing order of the extent of their ionization at equilibrium. Which of the above base is the strongest ?


Greater is the ionization constant (Kb) of a base, greater is the ionization of the base. Order of extent of ionization at equilibrium is dimethylamine > ammonia > pyridine > urea. Dimethylamine is the strongest base due to maximum value of Kb.
