Question

Given below are two statements.
Statement I: $O_2, Cu^{2+}, \;and\; Fe^{3+}$ are weakly attracted by magnetic field and are magnetized in the same direction as magnetic field.
Statement II: $NaCl$ and $H_2O$ are weakly magnetized in opposite directions to the magnetic field.
In the light of the above statements, choose the most appropriate answer from the options given below.

• 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.

Answer 1

Answer: (A)

Both Statement I and Statement II are correct.

Answer 2

$O_2, Cu^{2+} \;and\; Fe^{3+}$ have$2, 1$ and $5$ unpaired electrons respectively, so these are the paramagnetic species. Hence, they are attracted by magnetic field.
$NaCl$ and $H_2O$ are the diamagnetic species so they are repelled by the magnetic field.

The correct answer is (A): Both Statement I and Statement II are correct
