Which kind of isomerism is exhibited by octahedral Co(NH_(3))_(4)Br_(2)Cl?

Answer»

Geometrical and ionization
Geometrical and optical
Optical and ionization
Geometrical only.

Solution :`Ni(II)=3d^(8)4s^(0)`
Since the COMPLEX is paramagnetic, so the ligands do not induce pairing of d-orbitals and it would INVOLVE `sp^(3)` HYBRIDISATION forming tetrahedral geometry.

No. of unpaired electron = 2
Geometry : Tetrahedral.
