(A) The complexes are: $1$. $K_3[Co(NO_2)_6]$: Contains $[Co(NO_2)_6]^{3-}$,where $Co^{3+}$ is $d^6$ low-spin. It is yellow in color. Magnetic moment $\mu = \sqrt{n(n+2)} = 0 \ B.M.$ (since $n=0$). $2$. $K_4[Fe(CN)_6]$: Contains $[Fe(CN)_6]^{4-}$,where $Fe^{2+}$ is $d^6$ low-spin. It is pale yellow in color. Magnetic moment $\mu = 0 \ B.M.$ (since $n=0$). $3$. $K_3[Fe(CN)_6]$: Contains $[Fe(CN)_6]^{3-}$,which is red. $4$. $Cu_2[Fe(CN)_6]$: This is a brown/chocolate colored precipitate. $5$. $Zn_2[Fe(CN)_6]$: This is a white precipitate. The yellow complexes are $K_3[Co(NO_2)_6]$ and $K_4[Fe(CN)_6]$. The sum of their spin-only magnetic moments is $0 + 0 = 0 \ B.M.$

Complex	Structure and magnetic property
$i$. $NiCl_4^{2-}$	$p$. tetrahedral and diamagnetic
$ii$. $Ni(CO)_4$	$q$. tetrahedral and paramagnetic
$iii$. $PtCl_4^{2-}$	$r$. square planar and diamagnetic
$iv$. $Ni(CN)_4^{2-}$	$s$. square planar and paramagnetic

Consider the following low-spin complexes: $K_3[Co(NO_2)_6]$,$K_4[Fe(CN)_6]$,$K_3[Fe(CN)_6]$,$Cu_2[Fe(CN)_6]$,and $Zn_2[Fe(CN)_6]$. The sum of the spin-only magnetic moment values of complexes having yellow colour is $.......... B.M.$ (answer is nearest integer).
