Concept explainers
(a)
Interpretation:
Lewis acid and Lewis base are to be identified in the reaction of oxalate ion
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.
(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.
(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.
