Question

Which of the compounds above are strong enough acids to react almost completely with a hydroxide ion (pka of h2o = 15.74) or with a bicarbonate ion (pka of h2co3 = 6.37)? enter your answers as an alphabetized string, i.e. abc, not cba; enter none if none of the compounds are strong enough acids?

Answer 1

Answer:

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-
