Assertion : Due to Frenkel defect, density of the crystalline solid decreases. Reason : In Frenkel defect, cation or anion leaves the crystal.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion
  3. CIf assertion is true but reason is false
  4. DIf both assertion and reason are false.

Correct answer

D. If both assertion and reason are false.

Step-by-step solution

In a Frenkel defect an ion leaves its position in the lattice and occupies normally vacant interstitial position.
