Which of the following compounds is paramagnetic and colored?

Which of the following is not correctly matched?

Square planar complex of the type $MAXBL$ (where $A, B, X$ and $L$ are unidentate ligands) shows which of the following sets of isomers?

Which of the following square planar complex molecular formulas exhibits $cis-trans$ isomerism? ($a$ and $b$ are monodentate ligands)

For the octahedral complexes of $Fe^{3+}$ in $SCN^{-}$ (thiocyanato-$S$) and in $CN^{-}$ ligand environments,the difference between the spin-only magnetic moments in Bohr magnetons (when approximated to the nearest integer) is
[Atomic number of $Fe = 26$]

Match List $I$ with List $II$ :

List $I$ (Complex)	List $II$ (Type of isomerism)
$A$. $[Pt(NH_3)_2Cl_2]$	$I$. Optical
$B$. $[Co(en)_3]^{3+}$	$II$. Solvate
$C$. $[Co(NH_3)_5NO_2]Cl_2$	$III$. Geometrical
$D$. $[Cr(H_2O)_6]Cl_3$	$IV$. Linkage
