Concept explainers
(a)
Interpretation:
For the complex tetracarbonyldibromoiron(II) ion, chemical formula of the compound has to be written.
Concept Introduction:
Co-ordination compounds exhibit structural isomerism and stereoisomerism. Stereoisomerism deals with three dimensional spatial arrangements of atoms or groups of a molecule. There are two types of stereoisomerism – Geometric isomerism and optical isomerism.
A cis isomer has two same ligands lying adjacent to each other whereas a trans isomer has two same ligands lying opposite to each other.
In optical isomerism the isomer that rotates the plane of the polarized light in clockwise direction is termed as d-isomer and the isomer rotates the plane of the polarized light in anti-clockwise direction is l-isomer. These isomers are called optical isomers and they are non-superimposable mirror images.
(b)
Interpretation:
For the complex tetracarbonyldibromoiron(II) ion, possible number of geometric isomers has to be determined.

(c)
Interpretation:
For the complex tetracarbonyldibromoiron(II) ion whether the complex has optical isomers has to be ascertained.
