QNEET-2022-Ch-472: NEET 2022 Chemistry - Class 12 NEET-2022-Ch-472 Solution: Given below are two statements: Statement I: \(Cr^{2+}\) is…
Given below are two statements: Statement I: is oxidising and is reducing in nature. Statement II: compounds are repelled by the applied magnetic field. In the light of the above statements choose the most appropriate answer from the options given below
Multiple Choice Options
- A Statement I is incorrect but Statement II is correct
- B Both Statement I and Statement II are correct
- C Both Statement I and Statement II are incorrect
- D Statement I is correct but Statement II is incorrect
Step-by-Step Verified Solution
Statement I : Cr 2+ is reducing as its configuration changes from d 4 to d 3 , the latter having a half-filled t 2g level. On the other hand, the change from Mn 3+ to Mn 2+ results in the half-filled (d 5 ) configuration which has extra stability.
Statement II : Sc 3+ has zero unpaired electron, so magnetic moment is also zero. Hence, Sc 3+ will repelled by the applied magnetic field.
