Easy MCQ +4 / -1 PYQ · JEE Mains 2022

The incorrect statement about the imperfections in solids is :

  1. A Schottky defect decreases the density of the substance.
  2. B Interstitial defect increases the density of the substance.
  3. C Frenkel defect does not alter the density of the substance.
  4. D Vacancy defect increases the density of the substance. Correct answer

Solution

The vacancy defect increases the density of substance.<br/><br/> It does not change the density of the crystal. It only creates cationic vacancies. Frenkel Defect causes vacancy defect at its original site and an interstitial defect at its new location. Therefore, it does not change the density of the solid.
