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

Options

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

Answer

D

Explanation

If the species contain paired `e^-` , then it is said to be diamagnetic
