QNEET-2022-Ch-388: NEET 2022 Chemistry - Class 12 NEET-2022-Ch-388 Solution: Given below are two statements: one is labelled as Assertion…
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): In a particular point defect an ionic solid is electrically neutral even if few of its cations are missing from its unit cells. Reason (R): In an ionic solid Frankel defect arises due to dislocation of cation from its lattice site to interstitial site maintaining overall electrical neutrality. In the light of the above statements choose the most appropriate answer from the options given below
Multiple Choice Options
- A Both (A) and (R) are correct and (R) is the correct explanation of (A)
- B Both (A) and (R) are correct but (R) is not the correct explanation of (A)
- C (A) is correct but (R) is not correct
- D (A) is not correct but (R) is correct
Step-by-Step Verified Solution
_ Assertion statement is classic explanation of Schottky defect in which cation and anion leaves their site, or impurity defect.
_ Reason statement is true but not correct explanation as it is defining Frenkel defect in which ion does not leave crystal.
