Which is the correct statement for the given acids?

  1. A
    Phosphinic acid is a monoprotic acid while phosphonic acid is a diprotic acid.
  2. B
    Phosphinic acid is a diprotic acid while phosphonic acid is a monoprotic acid.
  3. C
    Both are triprotic acids
  4. D
    Both are diprotic acids

Solution & Step-by-step Explanation

- Phosphinic acid (Hypophosphorous acid, ) has only one group, so it is monoprotic.Phosphonic acid (Phosphorous acid, ) has two groups, so it is diprotic.Protic nature depends on the number of atoms attached directly to Oxygen.
