What type of isomerism is shown by the complex [Cr(en)2Cl2]+? (2023)

What type of isomerism is shown by the complex [Cr(en)2Cl2]+? (2023)

Step 1: Identify the complex. The complex is [Cr(en)2Cl2]+, where 'Cr' is chromium, 'en' is ethylenediamine, and 'Cl' is chloride.
Step 2: Understand the ligands. Ethylenediamine (en) is a bidentate ligand, meaning it can attach to the metal (Cr) at two points.
Step 3: Determine the geometry. The complex has a coordination number of 6, which typically leads to an octahedral geometry.
Step 4: Analyze the arrangement. In an octahedral complex with two bidentate ligands, the arrangement can create different spatial configurations.
Step 5: Identify optical isomerism. If the complex can form non-superimposable mirror images, it exhibits optical isomerism.
Step 6: Conclude. Since [Cr(en)2Cl2]+ can create such mirror images due to the bidentate nature of the ligands, it shows optical isomerism.
