The correct bond order in the following species is.
O2 O2+ O22+
O22+ O2+ O2-
O22+ , O2+ , O2
O2+ O2- O22+
O22+ O2+ O2-
The correct option is B.
Explanation of the correct option:
The electronic configuration of the ion-containing 18 electrons can be expressed as:
The electronic configuration of the containing 16 electrons can be expressed as:
The electronic configuration of the containing 16 electrons can be expressed as:
The electronic configuration of the ion-containing 17 electrons can be expressed as:
Hence, contains 3 electrons in the anti-bonding orbital and therefore it requires less energy to remove an electron from an anti-bonding orbital.
Hence, the correct bond order in the following species is .
