Interpretation Introduction

Interpretation:

The Lewis acid and Lewis base in compound ${\left[\text{Fe}{\left({\text{C}}_{\text{2}}{\text{O}}_{\text{4}}\right)}_{\text{3}}\right]}^{\text{3-}}$ formed from ${\text{Fe}}^{\text{3+}}$ and oxalate ion $\left({\text{C}}_{\text{2}}{\text{O}}_{\text{4}}{}^{2-}\right)$ should be identified.

Concept Introduction:

Reduction: If electrons are gained to a species during a chemical reaction. The species which gets electrons are said to be reduced.

Oxidation: If electrons are moved from a species during a chemical reaction. The species whose electrons are removed is said to be oxidized.

Lewis acid: The chemical species which accepts pair of electrons are termed as Lewis acid.

Lewis base: The chemical species which donates pair of electrons are termed as Lewis base.

Coordination compounds: The compounds having coordination covalent bonds which form when metal ions react with polar molecules or anions.

Ligands: The ions or molecules that forms coordination covalent bond with metal ions in a coordination compound.

Ligands should have minimum one lone pair of electron, where it donates two electrons to the metal. Metal atom accepts the electron pair from a ligand forming a coordination bond.

Bidentate ligand is ligands which donate two pair of electrons to form bond with metal.
