Is NO₃ a neutral ligand?

Hint: A ligand is an ion or molecule that donates a pair of electrons to the central metal atom or ion to form a coordination complex. The word ligand is from Latin, which means “tie or bind”. Ligands can be anions, cations, or neutral molecules. Chlorine atoms are the most neutral of all the elemental atoms because they don't have any electrons to give away.

Complete Step by Step Solution:
The nitrate ion \[N{o_3} - \] , which has a charge of \[ - 1\] , cannot be categorised as a neutral ligand. Its ligand has a negative charge. Neutral ligands that bind metal ions with high affinity for biological molecules are becoming important in biology and medicine.

They can be used as reagents for high-throughput screening and to determine cellular response to a drug - making them more efficient than methods that use radioactive isotopes as tracers. \[N{o_3}\] is a neutral ligand and it binds metals such as copper and zinc with high affinity. It's also a good choice when you need to search through a large number of compounds because it has low molecular weight and slow diffusion properties. Neutral ligands are ligands that are not bound by electrostatic forces. In contrast, positively charged or negatively charged ligands have the potential to interact with the protein due to electrostatic and hydrophobic forces. Neutral ligands are molecules that have no charge on them. They can be covalent or ionic ligands. Anionic pledge and neutral ligand: The general reaction of the anionic pledge with a neutral ligand proceeds through a stepwise mechanism.

Note: Neutral ligands will help in raising the expression of a gene without affecting its activity. This type of ligand can be used for molecular biology studies as an inhibitor or activator. Neutral ligands are a type of non-toxic ligands that have no measurable affinity for the receptor or ion channels, and have an electrophoretic mobility greater than \[5S\].
