Which of the following complexes exhibits geometrical isomerism? (2022) 2022
Step 1: Understand what geometrical isomerism is. It occurs when ligands (molecules attached to a central metal ion) can be arranged in different ways around the metal ion.
Step 2: Identify the complex in the question, which is [CoCl2(NH3)4]+. This complex has cobalt (Co) as the central metal ion.
Step 3: Look at the ligands attached to the cobalt ion. In this case, there are 2 chloride (Cl) ligands and 4 ammonia (NH3) ligands.
Step 4: Determine if the arrangement of these ligands can be different. Since there are two types of ligands (Cl and NH3), they can be arranged in different positions around the cobalt ion.
Step 5: Conclude that [CoCl2(NH3)4]+ can exhibit geometrical isomerism because the Cl ligands can be positioned differently relative to the NH3 ligands.
