Given below are two statements. Statement I: O2, Cu2+ and Fe3+ are weakly attracted by magnetic field and are magnetized in the same direction as magnetic field. Statement II: NaCl and H2O 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.

1. Both Statement I and Statement II are correct.
2. Both Statement I and Statement II are incorrect.
3. Statement I is correct but Statement II is incorrect.
4. Statement I is incorrect but Statement II is correct.

Correct answer: Both Statement I and Statement II are correct.

Solution

Both statements accurately describe the magnetic properties of the substances mentioned. Statement I correctly identifies O2, Cu2+, and Fe3+ as paramagnetic, meaning they are attracted to a magnetic field and align with it. Statement II correctly states that NaCl and H2O are diamagnetic, which means they are weakly repelled and align in the opposite direction to a magnetic field.
