Q39.Given below are two statements: Statement I : Frenkel defects are vacancy as well as interstitial defects. Statement II : Frenkel defect leads to colour in ionic solids due to presence of F-centres. Choose the most appropriate answer for the statements from the options given below: (1) Statement I is false but Statement II is true (2) Both Statement I and Statement II are false (3) Statement I is true but Statement II is false (4) Both Statement I and Statement II are true
What This Question Tests
This question assesses the understanding of the nature of Frenkel defects and the cause of color in ionic solids, distinguishing between Frenkel and F-center related phenomena.
