Assertion: Mond's process is based on the principle of complex formation between metal ions and ligands.
Reason: Carbonyl ligands readily form stable complexes with transition metal ions.

The assertion states that Mond's process is based on the principle of complex formation between metal ions and ligands. This assertion is true. Mond's process is a method used for the purification of nickel metal. It involves the reaction of impure nickel with carbon monoxide gas at high temperatures to form a volatile complex, nickel tetracarbonyl
. The volatile nature of the complex allows it to be easily separated and decomposed to obtain pure nickel metal.
The reason states that carbonyl ligands readily form stable complexes with transition metal ions. This reason is also true. Transition metals have vacant orbitals that can accept electron pairs from ligands. Carbon monoxide
is a well-known ligand that readily forms stable complexes with transition metal ions, known as carbonyl complexes.
However, the reason provided does not directly explain the assertion. While it is true that carbonyl ligands readily form stable complexes with transition metal ions, it does not specifically explain why Mond's process is based on complex formation between metal ions and ligands. Mond's process utilizes the unique volatility and reactivity of nickel tetracarbonyl, rather than solely focusing on the general property of carbonyl ligands.
