Given below are two statements.

Statement I: O2,Cu2+\mathrm{O}_{2}, \mathrm{Cu}^{2+} , and Fe3+\mathrm{Fe}^{3+} are weakly attracted by magnetic field and are magnetized in the same direction as magnetic field.

Statement II: NaCl\mathrm{NaCl} and H2O\mathrm{H}_{2} \mathrm{O} are weakly magnetized in opposite direction to magnetic field.

In the light of the above statements, choose the most appropriate answer from the options given below.

Multiple Choice Options

  • A Both Statement I and Statement II are correct.
  • B Both Statement I and Statement II are incorrect.
  • C Statement I is correct but Statement II is incorrect.
  • D Statement I is incorrect but Statement II is correct.

Step-by-Step Verified Solution

O2,Cu2+\mathrm{O}_{2}, \mathrm{Cu}^{2+} and Fe3+\mathrm{Fe}^{3+} have 2,1 and 5 unpaired electrons respectively, so these are the paramagnetic species. Hence, they are attracted by magnetic field.

NaCl\mathrm{NaCl} and H2O\mathrm{H}_{2} \mathrm{O} are the diamagnetic species so they are repelled by the magnetic field.
