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 $H _2 O$ 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 :

• 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)

$O _2, Cu ^{2+}$ and $Fe ^{3+}$ are paramagnetic,
$\therefore$ Weakly attracted by magnetic field.
$NaCl$ and $H _2 O$ are diamagnetic,
$\therefore$ Weakly repelled by magnetic field.
