Question

Among the following which compound will show the highest
lattice energy ?
(a) KF (b) NaF (c) CsF (d) RbF

Answer 1

NaF has the highest  lattice energy.

Option (B) is correct.

Explanation:

• The compound which shows the highest lattice energy is NaF.

• It is n organic compound having white or colorless crystals and it is readily soluble in water.

• NaF has high lattice energy because Na+ has smallest size and lattice energy increases as the size of the cation decreases.

• It is the most common source of fluoride in pharmaceutical products.

• It is also used in the prevention dental cavities.
