Chapter 20, Problem 20.12QP

1. a)

Interpretation Introduction

Interpretation: The given complex ion ${{\text{[Cr(C}}_{\text{2}}{\text{O}}_{\text{4}}{\text{)}}_{\text{2}}{{\text{(H}}_{\text{2}}\text{O)}}_{\text{2}}\text{]}}^{\text{-}}$ of a coordination compound to be interpreted.

Concept Introduction:

Lewis acid: The species which accepts the lone pair of electrons.

Lewis base: The species which donates lone pair of electrons.

Donor atom: The neutral molecule or the negatively charged species which donates pair of electrons is known as Donor atom.

Coordinate covalent bonds: A covalent bond in which the Ligand donates both electrons to the metal ion to construct a bonding interaction known as coordinate covalent bond.

To Identify: The given complex ion ${{\text{[Cr(C}}_{\text{2}}{\text{O}}_{\text{4}}{\text{)}}_{\text{2}}{{\text{(H}}_{\text{2}}\text{O)}}_{\text{2}}\text{]}}^{\text{-}}$ of a coordination compound to be interpreted.
