(a)

Interpretation Introduction

Interpretation: The color of the complex and the reason has to be explained.

Concept introduction:

Spectrochemical series:  A list of ligands ordered in the basis of ligand strength.

${\text{I}}^{\text{-}}\text{<}{\text{Br}}^{\text{-}}\text{<}{\text{Cl}}^{\text{-}}\text{<}{\text{F}}^{\text{-}}{\text{< OH}}^{\text{-}}{\text{< H}}_{\text{2}}{\text{O < NH}}_{\text{3}}\text{< en <}\text{}{\text{CN}}^{\text{-}}\text{<}\text{}\text{CO}$

Paramagnetic property: The presence of unpaired electrons in the electronic configuration of the metal ion in coordination complex.

Diamagnetic property: The absence of unpaired electrons of the metal ion in coordination compound which do repel by the magnet.

(b)

Interpretation Introduction

Interpretation: Carbonate ion is weak or strong- field ligand has to be identified.
