Concept explainers
(a)
Interpretation:
The type of isomerism is to be determined in the complex [CrBr2(en)2]+.
Concept introduction:
The word isomerism is used to represent the compounds and ions which are formed by the same kind of atoms and the same number of atoms. But these compounds, ions or radicals are different from each other in terms of structure.
(b)
Interpretation:
The type of isomerism is to be determined in the complex [Cobra (ox)2(SCN)] 3+.
Concept introduction:
The word isomerism is used to represent the compounds and ions which are formed by the same kind of atoms and a same number of atoms. But these compounds, ions or radicals are different from each other in terms of structure.
(c)
Interpretation:
The type of isomerism is to be determined in the complex [NiCl4(en)]2-.
Concept introduction:
The word isomerism is used to represent the compounds and ions which are formed by the same kind of atoms and a same number of atoms. But these compounds, ions or radicals are different from each other in terms of structure.
(d)
Interpretation:
The type of isomerism is to be determined in the complex [PtBrCl(ox)]-.
Concept introduction:
The word isomerism is used to represent the compounds and ions which are formed by the same kind of atoms and a same number of atoms. But these compounds, ions or radicals are different from each other in terms of structure.
(e)
Interpretation:
The type of isomerism is to be determined in the complex [Cr(Cl)2(det)] where det is H2N(CH2)2NH(CH2)2NH2.
Concept introduction:
The word isomerism is used to represent the compounds and ions which are formed by the same kind of atoms and a same number of atoms. But these compounds, ions or radicals are different from each other in terms of structure.
