Given below are two statements: Statement I: Cr2+\mathrm{Cr}^{2+} is oxidising and Mn3+\mathrm{Mn}^{3+} is reducing in nature. Statement II: Sc3+\mathrm{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:Given below are two statements: Statement I: Cr^ 2+ is oxidising and Mn^ 3+ is reducing in nature. Statement II: Sc^ 3+

Options

  1. ABoth Statement I and Statement II are correct
  2. BBoth Statement I and Statement II are incorrect
  3. CStatement I is correct but Statement II is incorrect
  4. 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

Given below are two statements: Statement I: Cr^ 2+ is oxidising and Mn^ 3+ is reducing in nature. Statement II: Sc^ 3+
Half filled dd-orbital (more stable) Therefore, Mn3+\mathrm{Mn}^{3+} acts as an oxidising agent. Sc3+\mathrm{Sc}^{3+} - [Ar] All elements are paired making it diamagnetic. Hence Sc3+\mathrm{Sc}^{3+} compounds are repelled when placed in an external magnetic field.
