Concept explainers
(a)
Interpretation:
The reason for oxalic acid to be used as arust stain remover needs to be explained.
Concept introduction:
Oxalic acid is an organic compound with the chemical formula (COOH)2 . It is a colorless crystalline solid which is known to form colorless solution when mixed with water. It has a vast number of applications including cleaning of rust. Rust is nothing but other name of iron oxide and it is formed when iron or alloys of iron get exposed to moisture and oxygen for a long period of time.
(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
(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.
(d)
Interpretation:
The reason for oxalate ion to act as a chelating agent 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.
(e)
Interpretation:
The reason for the ammonia to act as a ligand but not ammonium ion 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.
