Which of the following complexes show linkage isomerism?

Ambidentate ligands have more than one binding site. Both NO₂ and SCN are ambidentate ligands and will therefore show linkage isomerism.

1) SCN^-→ M NCS→M

Isothiocyanato Thiocyanato

2) MßNO₂ MßO-N=O

Nitrito-N Nitrito-O

Arrange the following complexes in the increasing order of conductivity of

their solution: [Co(NH3)3Cl3], [Co(NH3)4Cl2] Cl, [Co(NH3)6]Cl3 , [Cr(NH3)5Cl]Cl2

A coordination compound CrCl3.4H2O precipitates silver chloride when treated

with silver nitrate. The molar conductance of its solution corresponds to a

total of two ions. Write structural formula of the compound and name it.
