Q. The magnetic moment of an octahedral homoleptic Mn(II) complex is $5.9\, BM$. The suitable ligand for this complex is :

JEE MainJEE Main 2019Coordination Compounds

Solution:

$\mu = 5.9 BM \, \therefore \, n$ (no of unpaired.e-) = 5
Cation $Mn^{II} - 3d^{5}$ confn only possible for relatively weak ligand.
$\therefore $ $NCS^-$
