1.	Give the name, the stereochemistry and the magnetic behaviour of the following complexes:(i) [Co (NH3 )5 Cl]Cl2(ii) K2 [Ni (CN) 4 ]
Answer» (i) [Co(NH₃)₅Cll]Cl₂: Pentaamminechlorido cobalt (III) chloride Co(III): [Ar] 3d⁶ 4s^o —d²sp³ hybridisation leads to octahedral shape. Magnetic behaviour: Diamagnetic. (ii) K₂[Ni(CN)₄]: Potassium tetracyano nickelate (II) Ni(II): [Ar] 3d⁸4s° —dsp² hybridisation leads to square planar shape. Magnetic behaviour: Diamagnetic.

Give the name, the stereochemistry and the magnetic behaviour of the following complexes:(i) [Co (NH3 )5 Cl]Cl2(ii) K2 [Ni (CN) 4 ]

Answer»

(i) [Co(NH₃)₅Cll]Cl₂: Pentaamminechlorido cobalt (III) chloride

Co(III): [Ar] 3d⁶ 4s^o —d²sp³ hybridisation leads to octahedral shape.

Magnetic behaviour: Diamagnetic.

(ii) K₂[Ni(CN)₄]: Potassium tetracyano nickelate (II)

Ni(II): [Ar] 3d⁸4s° —dsp² hybridisation leads to square planar shape.

Magnetic behaviour: Diamagnetic.
