What are inert and labile ligands?
Inert ligands are stable ligands that do not easily dissociate from the metal center, while labile ligands are more reactive and can readily dissociate from the metal center. Inert ligands typically form stable and kinetically inert complexes, while labile ligands can undergo substitution reactions more easily.
What is trans -effect?
Trans-effect in inorganic chemistry is defined as the effect where some ligands are able to influence properties of the ground states where they are trans. It is when some ligands can be seen as trans-directing ligands.
Write a short notes on spectro chemical series?
The spectrochemical series ranks ligands based on their ability to produce a strong ligand field in coordination complexes. Strong ligands create a large energy gap between the eg and t2g orbitals, leading to low-spin complexes with paired electrons in the eg orbitals. Ligands at one end of the series, such as CN- and CO, are considered strong field ligands, while ligands at the other end, like F- and H2O, are weak field ligands.
Are ligands complex ions?
No, ligands are not complex ions. Ligands are molecules or ions that can donate electrons to form coordinate bonds with a central metal ion to create a coordination complex. In contrast, complex ions are ions formed from a central metal ion bonded to surrounding ligands.
What is a zwitter iron?
A zwitterion is a molecule that has a positive and negative charge on different parts of the molecule. Iron can form zwitterions in certain chemical environments due to its ability to undergo redox reactions and coordinate with ligands.
What is the definition of an anionic ligand?
An anionic ligand is a ligand that carries a negative charge. It can donate electron pairs to form coordinate bonds with a central metal ion or atom in a coordination compound. Examples include chloride (Cl-), sulfate (SO4^2-), and cyanide (CN-).
What are the advantages of multidentate ligands over their unidentate counterparts?
multidentate ligands can be good chelating ligands compare to unidendate multidentate ligands bring better stability to the central metal

Why do only 4 ammonia ligands and 2 water ligans bind around the copper ii ion rather than substitution of all 6 water ligands?
The ligand substitution process is determined by the relative ligand strengths and steric hindrances. In the case of copper(II), ammonia ligands are stronger ligands compared to water, leading to preferential substitution of water ligands by ammonia ligands due to thermodynamic factors. Additionally, steric hindrance may limit the number of ligands that can bind around the central copper ion.
What are pi acceptor ligand?
Pi acceptor ligands are ligands that can accept electron density from a metal center via their pi orbitals. These ligands typically have pi bonding interactions with the metal, allowing for back-donation of electron density from the metal to the ligand. Pi acceptor ligands are often strong-field ligands that influence the electronic structure and reactivity of metal complexes.
What is weak field ligands?
Weak field ligands are ligands that result in a small Δ (delta) value in transition metal complexes, leading to high-spin configurations. These ligands typically have small crystal field splitting energies and weaker interactions with the metal ion, allowing for more unpaired electrons in the d orbitals. Examples of weak field ligands include F-, Cl-, and H2O.
What is trans -effect?
Trans-effect in inorganic chemistry is defined as the effect where some ligands are able to influence properties of the ground states where they are trans. It is when some ligands can be seen as trans-directing ligands.

What are the ligands present in an inorganic complex compound?
Ligands in inorganic complex compounds are ions or molecules that bond to a central metal atom. Common ligands include water (H2O), ammonia (NH3), chloride (Cl-), and cyanide (CN-). These ligands donate electron pairs to the metal atom, forming coordination bonds.
What is ancillary ligand?
An ancillary ligand is a ligand on a chemical complex that is not directly involved in the chemistry. Ancillary ligands are often there to help stabilize a complex or contribute steric or electronic effects. Thus, activity of a complex can be tuned by adjusting the ancillary ligands, even though they are not directly a part of the chemistry that is occurring. The ligands that are involved in the chemistry are called functional ligands.
