The bond order and magnetic behaviour of O2− ion are, respectively : (1) 1.5 and paramagnetic (2) 1.5 and diamagnetic (3) 2 and diamagnetic (4) 1 and paramagnetic
- 1.5 and paramagnetic
- 1.5 and diamagnetic
- 2 and diamagnetic
- 1 and paramagnetic
Correct answer: 2 and diamagnetic
Solution
The O2− ion has a bond order of 1.5, indicating a stable bond between the oxygen atoms, and it is diamagnetic because all its electrons are paired, resulting in no net magnetic moment.
