Concept explainers
(a)
Interpretation:
The Lewis acid and Lewis base needs to be identified in the reaction of ethylenediamine with
Concept introduction:
The molecules which donate the electrons are known as Lewis bases while the molecules which accept the electrons are known as Lewis acids.
(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.
