(b)

Interpretation:

The reason for the tetrahedral complexes to have no geometrical isomers needs to be explained.

Concept introduction:

Coordination compounds are those in which a transition metal atom is bonded to a ligand which can be neutral, cation or anion. The transition metal element is enclosed within a bracket and a charge is present on the ion to balance the charge present on the ligands. Geometrical isomerism refers to the type of isomerism where the isomers differ in only the spatial arrangement of the ligands attached to the central metal atom.

Interpretation Introduction

(c)

Interpretation:

The reason for the Co²⁺ions to act as a areLewis acids needs to be explained.

Concept introduction:

Metal cations are formed when a metal looses one or more electrons in order to attain stable electronic configurations. Lewis acids are those chemical species which have the tendency to accept electron pairs.
