Solution
Correct Answer:
is a stronger Lewis base ligand than H2O
Ammonia donates electron density more effectively than water and forms stronger coordinate bonds with Cu2+. Stronger metal-ligand interaction increases complex stability, so tetraamminecopper(II) is favored over the aqua complex.
This hard difficulty chemistry question is from the chapter coordination compounds, covering the topic of stability of complexes. It appeared in the 2025 exam.
