All of the following complex show decrease in their weight when placed in magnetic balance then the group of complexes having tetrahedral geometry is I) Ni(CO)_(4)II) K[AgF_(4)]III) Na_(2)[Zn(CN)_(4)] IV) K_(2)[Pt(Cl_(4)]V) [RhCl(pph_(3))_(3)]

Answer»

II, III, IV
I, II, III
I, III, IV
None

Solution :I) `[Ni(CO)_(4)]`- tetrahedral
II) `K[AgF_(4)]`- square planar.
III) `Na_(2)[Zn(CN)_(4)]`- tetrahedral.
IV) `K_(2)[PtCl_(4)]`- square planar.
V) `[RHCL(PPh_(3))_(3)]`- square planar.
