Given below are two statements.
Statement I : $\mathrm{O}_{2, a, \mathrm{Cu}^{2+}}$ and $\mathrm{Fe}^{3+}$ are weakly attracted by magnetic field and are magnetized in the same direction as magnetic field.
Statement II : NaCl and $\mathrm{H}_2 \mathrm{O}$ are weakly magnetized in opposite direction to magnetic field. In the light of the above statements, choose the most appropriate answer form the options given below :
Select the correct option:
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.
✓ Correct! Well done.
✗ Incorrect. Try again or view the solution.
Solution
Sol. $\mathrm{O}_2, \mathrm{Cu}^{2+}$ and $\mathrm{Fe}^{3+}$ are paramagnetic,
∴ Weakly attracted by magnetic field.
NaCl and $\mathrm{H}_2 \mathrm{O}$ are diamagnetic,
∴ Weakly repelled by magnetic field.
