Which amongst the following is an incorrect statement?

  1. A.O2+\mathrm{O_2^+} ion is diamagnetic✓
  2. B.The bond orders of O2+\mathrm{O_2^+}, O2\mathrm{O_2}, O2−\mathrm{O_2^-} and O22−\mathrm{O_2^{2-}} are 2.5, 2, 1.5 and 1, respectively
  3. C.The C2\mathrm{C_2} molecule has four electrons in its two degenerate π\pi molecular orbitals
  4. D.H2+\mathrm{H_2^+} ion has one electron

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
