Q1 / 120 · VITEEE 2017 · Chemistry

Schottky defect in crystals is observed when

  • A
    unequal number of cations and anions are missing from the lattice
  • Correct answer
    B
    equal number of cations and anions are missing from the lattice
  • C
    an ion leaves its normal site and occupies an interstitial site
  • D
    density of the crystal is increased

Solution

It is stoichiometric defect and it is observed when equal number of cations and anions are missing from the lattice site.

Hence, the correct answer is option: 'B'.
