Question

Why ammonia is a good ligand?

Answer 1

Ammonia:

1. Ammonia is a colourless, flammable gas with a strong odour.
2. It can be found in nature, primarily as a result of anaerobic degradation of plant and animal materials, and it has also been discovered in space.
3. Plants, primarily legumes, use rhizobia bacteria to "fix" atmospheric nitrogen and generate ammonia.

Reason for Ammonia a Good Ligand:

1. Ammonia acts as a ligand due to the lone pair of electrons in nitrogen. It is simple to build coordinate bonds with the lone electron pair.
2. Ammonia acts as a ligand because it has one lone pair on it, as shown in the diagram.
3. Ammonia (almost $N{H}_3$) is a Lewis base with a lone pair of electrons on the nitrogen atom.
4. Although ammonia is a weak field ligand, it occasionally exhibits robust field ligand behaviour (example: for Cobalt). Ammonia is a weak field ligand for Fe. As a result, no pairing occurs. Ammonia acts as a ligand because nitrogen has a lone pair of electrons. It is simple to build coordinate bonds with a single electron pair. Ammonia functions as a ligand because it contains one single pair on it, as shown in the diagram.
5. Ammonia (almost $N{H}_3$) is a Lewis base and possesses a single electron on the nitrogen atom. Ammonia functions as a ligand and establishes coordination connections with species lacking in electrons, even though the electron pair can be immediately given.
