(a)

Interpretation Introduction

Interpretation:

Whether the given ligand is monodentate, bidentate or tridentate has to be classified.

Concept Introduction:

Monodentate ligands:

These are the ligands which will bind with metal by their electron pair of single donor atom.

$\begin{array}{l}\text{Examples:}\\ {\text{H}}_{\text{2}}\text{O}\text{,}{\text{NH}}_{\text{3}}\text{,}{\text{Cl}}^{\text{-}}\text{,}{\text{CN}}^{\text{-}}\text{,}\text{CO}\text{,}{\text{NCS}}^{\text{-}}\text{and}{\text{OH}}^{\text{-}}\end{array}$

Bidentate ligands:

These are the ligands which will bind with metal by their electron pair of two donor atoms.

$\begin{array}{l}\text{Examples:}\\ \text{ethylenediamine}\left(\text{en}\right)\text{,}\text{glycinate}\text{ion}\left({\text{gly}}^{\text{-}}\right)\text{and}\text{oxalate}\text{ion}\end{array}$

Tridentate ligands:

These are the ligands which will bind with metal by their electron pair of three donor atoms.
