Question

The number of geometrical isomers for [Pt(NH₃)₂Cl₂] is ______.

Options

• two

• one

• three

• four

Answer 1

The number of geometrical isomers for [Pt(NH₃)₂Cl₂] is two.

Explanation:

[Pt(NH₃)₂Cl₂] has 2 geometrical isomers:

• Cis-isomer: Both Cl ions are adjacent to each other.
• Trans-isomer: The Cl ions are opposite to each other.

These different arrangements occur due to platinum’s square planar geometry.
