Question

The total number of possible isomers for [Pt(NH₃)₄Cl₂]Br₂ is ______ (nearest integer).

Answer 1

The total number of possible isomers for [Pt(NH₃)₄Cl₂]Br₂ is 6 (nearest integer).

Explanation:

The complex [Pt(NH₃)₄Cl₂]Br₂ can have 6 isomers due to a combination of geometrical isomerism and ionization isomerism:

1. Geometrical isomerism: The two chloride ions (Cl⁻) can be arranged in two possible ways around the central platinum ion. (cis and trans)
2. Ionization isomerism: The two Br⁻ ions can either be outside or inside the coordination sphere, leading to different isomers.

Thus, combining cis-trans isomerism and ionization isomerism, there are 6 possible isomers.
