Question

Which of the following compounds exhibits linkage isomerism?

पर्याय

• [Co(en)₃]Cl₃

• [CoCl₂(en)₂]⁺

• [CoCl(en)₂NO₂]Br

• [Co(NH₃)₅Cl]Br₂

Answer 1

[CoCl(en)₂NO₂]Br

Explanation:

Because the ambidentate ligand NO₂ can be attached by either N or O as a donor atom, two linkage isomers exist: [COCl(en)₂NO₂]Br and [CoCl(en)₂ONO]Br.
