All the following complexes show decrease in their weights when placed in a magnetic balance then the group of complexes having tetrahedral geometry is :
`Ni(CO)_(4)`
`K[AgF_(4)]`
`Na_(2)[Zn(CN)_(4)]`
`K_(2)[PtCl_(4)]`
`[RhCl(PPh_(3))_(3)]`

Options

A. (ii)(iii),(v)
B. (i),(iii) , (iv)
C. (i),(iii),(iv)
D. None of these

Answer

D

Explanation

`NI(CO)_4 -sp^3`(Co is strong field ligand , `overset(+3)([Ag F_4]^-)dsp^2`(`4d^8` electron configuration) ,
`[Zn(CN)_4]^2 -sp^3`(`3d^10` electron configuration) ,`[PtCl_4]^(3-) -dsp^2` (`5d^8` electron configuration) ,
`[RhCl(PPh_3)_3] -dsp^2` (`4d^8` electron configuration)
All complexes are diamagnetic in nature which show decreases in their weights in magnetic field.
