Question

Which of the following complex can show both geometrical and optical isomerism ?
Options
1. [NiF.ClBr.I]–2
2. [Fe(OX)3]–3
3. [Ni(dmg)2]
4. [Fe(OX)2.Cl2]–3
PLEASE EXPLAIN THE REASONS PROPERLY.

Answer 1

Explanation:

Due to the irrotational nature of bidentate ligands, optical isomerism can be seen in this complex. The structures are as follows: So, we come to the conclusion that the only compound that shows both geometrical and optical isomerism is [Co(en)2Cl2]+. So, the correct answer is “Option A”.
