Ammonia is a Lewis base. It forms complexes with cations of transition elements. Pb2+ does not form a complex with ammonia as lead (Pb) is not a transition element. Lead (Pb) is a p - block element.

Answer:
Introduction:
Ammonia (NH3) is a Lewis base, as it donates an electron pair to form a coordinate bond with a Lewis acid. It can form complexes with various cations by acting as a ligand.
Explanation:
Complex Formation:
Complex formation occurs when a ligand (such as ammonia) donates a pair of electrons to a metal cation, forming a coordinate bond. This results in the formation of a metal-ligand complex. Most cations can form complexes with ammonia, but one of the given cations does not.
The Cations:
Let's analyze each cation to determine whether or not it forms a complex with ammonia.
- Ag (Silver):
Silver cation (Ag+) can form complexes with ammonia. It has a vacant d-orbital that can accept a lone pair of electrons from ammonia, forming a complex.
- Cu2+ (Copper):
Copper cation (Cu2+) can also form complexes with ammonia. It has a vacant d-orbital that can accept a lone pair of electrons from ammonia, forming a complex.
- Cd2+ (Cadmium):
Cadmium cation (Cd2+) can form complexes with ammonia. It has a vacant d-orbital that can accept a lone pair of electrons from ammonia, forming a complex.
- Pb2+ (Lead):
Lead cation (Pb2+) does not form a complex with ammonia. It does not have vacant d-orbitals to accept the electron pair from ammonia. Therefore, option D is the correct answer.
Conclusion:
In conclusion, among the given cations, the one that does not form a complex with ammonia is Pb2+ (Lead). The other cations, Ag+, Cu2+, and Cd2+, can all form complexes with ammonia by accepting a lone pair of electrons.
