Consider the following six electronic configurations (remaining inner orbitals are completely filled) and mark the incorrect option.

Options

A. Stability order: `II gt I gt IV gt III`
B. Order of spin multiplicity: `IV gt III =I gt II`
C. V does not violate all the three rules of electronic configuration
D. If VI represents A and `A^(+)` when kept near a magnet, `A^(+)` acts as diamagnetic substance.

Answer

B

Explanation

Electrons filling rules and stability concept spin multiplicity `= 2s +1`
