Passage / Comprehension

Complex compounds that have the same molecular formula but have different structural/space arrangements of ligands around central metal atom/ion are called isomers, these are of two types namely structural and stereoisomers.

Complex species that exhibits isomerism is/are :

Options:(select one or more)

Answer:

B, D

Solution:

$[C o (N H_{3})_{5} (N O_{3})]^{2 +}$ does not show isomerism because it contains only one ambidentate ligand coordinated through a fixed atom. $[Pt (N H_{3})_{4}] [PtC l_{4}]$ shows coordination isomerism due to the interchange of ligands between the complex cation and anion. $[Pt (e n) C l_{4}]$ does not show geometrical isomerism because the bidentate ligand en fixes adjacent positions in a square planar complex. $[C o (e n)_{2} (H_{2} O) B r]^{2 +}$ shows geometrical (cis/trans) as well as optical isomerism. Therefore, the correct answer is B and D.
