JEE Main 27 July 2022, Shift 1, Chemistry Q62

Question 62 of 90 in this shift, Chemistry question 2 of 30, Section A.

Given below are two statements. Statement I: O2\mathrm{O_2}, Cu2+\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 and H2O\mathrm{H_2O} 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. (1)Both Statement I and Statement II are correct.Official answer
  2. (2)Both Statement I and Statement II are incorrect.
  3. (3)Statement I is correct but Statement II is incorrect.
  4. (4)Statement I is incorrect but Statement II is correct.
