Which among the following statements is NOT true about Frenkel defect?

Which among the following statements is NOT true about Frenkel defect?
  1. It occurs in ionic compounds with sizes of cations and anions almost equal.
  2. The density of solid crystal and its chemical properties remain unchanged as no ions are missing from the crystal lattice as a whole.
  3. The crystal as whole remains electrically neutral because equal number of cations and anions are present.
  4. The ions of ionic compound must have low co-ordination number.

Solution

It occurs in an ionic compound in which size of cation is smaller than anions.
