NEET2022ChemistryCoordination CompoundsActual
Given below are two statements: Statement I: Cr ²⁺ is oxidising and Mn ³⁺ is reducing in nature. Statement II: Sc ³⁺ 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:
Options
- ABoth Statement I and Statement II are correct
- BBoth Statement I and Statement II are incorrect
- CStatement I is correct but Statement II is incorrect
- DStatement I is incorrect but Statement II is correct
Correct answer
D. Statement I is incorrect but Statement II is correct
Step-by-step solution
Half filled d -orbital (more stable) Therefore, Mn ³⁺ acts as an oxidising agent. Sc ³⁺ - [Ar] All elements are paired making it diamagnetic. Hence Sc ³⁺ compounds are repelled when placed in an external magnetic field.
