Pyridinium will react with both OH - and HCO3-, whereas the ketones will only react with concentrated OH-, while Butan-2-one cannot react with either of above.

a) Butan-2-one: cannot react with both hydroxide ion and bicarbonate.

b) Pyridinium: can react with both hydroxide ion and bicarbonate.

c) ketones : can only react with concentrated OH-
