Chapter 21, Problem 21.75SP

Interpretation Introduction

(a)

Interpretation:

Lewis acid and Lewis base are to be identified in the reaction of oxalate ion $({\text{C}}_{\text{2}}{\text{O}}_4^{2-})$ with ${\text{Fe}}^{3+}$ which results in ${{\text{[Fe(C}}_{\text{2}}{\text{O}}_{\text{4}}{\text{)}}_{\text{3}}]}^{3-}$

Concept introduction:

The molecules which donate the electrons are known as Lewis base while the molecules which accepts the electrons are known as Lewis acid.

Interpretation Introduction

(b)

Interpretation:

The ligands and donor atoms are to be identified.

Concept introduction:

Ligand can be defined as the ion and molecule which have the tendency to donate the electrons to the central atom or ion.

Interpretation Introduction

(c)

Interpretation:

The coordination number and geometry of the metal present in the complex are to be determined.

Concept introduction:

The coordination number can be defined as the number of ligands attached to the central atom by coordinate bonds.
