Q21 / 180 · KCET 2021 · Chemistry

The correct statement regarding defects in solid is

  • A
    Frenkel defect is a vacancy defect
  • B
    Schottky defect is a dislocation defect
  • Correct answer
    C
    Trapping of an electron in the lattice leads to the formation of F-centre
  • D
    Schottky defect has no effect on density

Solution

The correct statements regarding defects in solid is trapping of an electron in the lattice which leads to the formation of F-centre. Other statements are incorrect, because Frenkel defect is dislocation defect and density decreases in case of Schottky defect as it is a vacancy defect.

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