Among the following, which is water insoluble?

Options

  1. ASodium fluoride
  2. BPotassium fluoride
  3. CBeryllium fluoride
  4. DMagnesium fluoride

Correct answer

D. Magnesium fluoride

Step-by-step solution

The fluorides of alkaline earth metals except beryllium fluoride are insoluble in water because of large values of their lattice energy. Hence magnesium fluoride is insoluble in water.
