Question
All the following complexes show decrease in their weights when placed in a magnetic balance then the group of complexes having tetrahedral geometry is :
I Ni (CO)4 II K [AgF4] III Na2 [Zn (CN)4]
IV K2 [PtCl4] V [RhCl (PPh3)3]
I Ni (CO)4 II K [AgF4] III Na2 [Zn (CN)4]
IV K2 [PtCl4] V [RhCl (PPh3)3]
Options
A.II, III, V
B.I, II, III
C.I, III, IV
D.none of these
Solution
(i) It is tetrahedral (sp3) because there is no (n-1)d orbital vacant for dsp2 hybridisation.
(ii) Ag with +3 oxidation state and 4d8 configuration has square planar geometry.
(iii) It is tetrahedral (sp3) because there is no (n-1)d orbital vacant for dsp2 hybridisation.
(iv) Pt with +2 oxidation state and 5d8 configuration has square planar geometry.
(v) Rh with +1 oxidation state and 4d8 configuration has square planar geometry.
When we place these complexes in a magnetic balance, then there is decrease in their weights. This indicates that the complexes are dimagnetic.
