For a transition metal with a $d^7$ configuration,the magnetic susceptibility (magnetic moment) is ........ $B.M.$

What is the magnetic moment (in $B.M.$) of ${K_3}[FeF_6]$?

The spin-only magnetic moment of $[Mn(H_2O)_6]^{2+}$ complex is $........ \ B.M.$ (Nearest integer) (Given: Atomic number of $Mn$ is $25$)

The following complexes are given:
$1$. $\text{trans}-[Co(NH_3)_4Cl_2]^+$
$2$. $\text{cis}-[Co(NH_3)_2(en)_2]^{3+}$
$3$. $\text{trans}-[Co(NH_3)_2(en)_2]^{3+}$
$4$. $[NiCl_4]^{2-}$
$5$. $[TiF_6]^{2-}$
$6$. $[CoF_6]^{3-}$
Choose the correct code:

Which of the following octahedral complexes does not exhibit geometrical isomerism? ($A$ and $B$ are monodentate ligands)

Which of the following will have a spin-only magnetic moment of $2.86 \ BM$?
