Carbon monoxide (CO) is isoelectronic with :
N2
Two species are isoelectronic when they contain the same total number of electrons (and, for diatomics, the same molecular-orbital configuration). Carbon monoxide has 6 + 8 = 14 electrons, with the configuration that gives a bond order of 3.
Step 1 — N2: 7 + 7 = 14 electrons, bond order 3, the same as CO. Step 2 — O2: 8 + 8 = 16 electrons. Step 3 — NO: 7 + 8 = 15 electrons. Step 4 — CN+: 6 + 7 − 1 = 12 electrons.
Only dinitrogen matches the 14-electron count of carbon monoxide; this is why N2 and CO have similar bond orders, similar bond energies and comparable vibrational frequencies. O2 has two extra electrons in π* orbitals (bond order 2), NO has one extra π* electron (bond order 2.5), and the cation CN+ is two electrons short of CO, so none of these three is isoelectronic with CO.
N2 option is correct.
