(A) Multiplicity is defined as $2|S| + 1$,where $S$ is the total spin quantum number.For a $d^5$ configuration,there are $5$ electrons.To achieve maximum multiplicity,all electrons must have parallel spins $(S = 5 	imes \frac{1}{2} = \frac{5}{2})$.Maximum multiplicity $= 2(\frac{5}{2}) + 1 = 6$.To achieve minimum multiplicity,the spins should be paired as much as possible.For $5$ electrons,$2$ pairs of electrons have opposite spins $(+1/2, -1/2)$ and $1$ electron remains unpaired $(S = 1/2)$.Minimum multiplicity $= 2(\frac{1}{2}) + 1 = 2$.

Assuming Hund's Rule is not necessarily followed for a $d^5$ configuration,what could be the maximum and minimum multiplicity possible?
