Which type of ligand is Ammine?
In coordination chemistry, metal ammine complexes are metal complexes containing at least one ammonia (NH3) ligand.
What is lability and inertness?
Labile – a compound that undergoes reactions with a relatively high rate of. substitution. Inert – a compound that undergoes reactions with a slow rate of substitution.
What is ligand exchange reaction give example?
If you add concentrated hydrochloric acid to a solution containing hexaaquacobalt(II) ions (for example, cobalt(II) chloride solution), the solution turns from its original pink color to a dark rich blue. The six aqua molecules are replaced by four chloro ions. The reaction taking place is reversible.
What are labile and inert complexes give examples?
It can be seen that d4 low spin are also labile in nature. On the other side, d3 and d8 metal complexes are inert in nature and undergo slow ligand displacement through the associative pathway. Moreover, low spin complexes with d5 and d6 metal complexes are also inert due to the loss of CFSE during the SN1 mechanism.
Which type of ligand is ammine NH3 *?
strong field ligand
Ammonia (NH3) is known to be a strong field ligand since the donor atom in this case is nitrogen.
What is the difference between labile and non labile complexes?
The key difference between inert and labile complexes is that inert complexes undergo slow substitution, whereas labile complexes undergo rapid substitution.
What causes ligand exchange?
A ligand exchange (also ligand substitution) is a type of chemical reaction in which a ligand in a compound is replaced by another. One type of pathway for substitution is the ligand dependent pathway. In organometallic chemistry this can take place via associative substitution or by dissociative substitution.
What is ligand substitution reaction?
In ligand substitution reactions, one or more ligands around a metal ion are replaced by other ligands. In many ways, all inorganic reactions can be classified as either substitution or oxidation-reduction reactions, so that substitution reactions represent a major type of inorganic process.
What is meant by inert complex?
Inert Complex is the transition metal complex ion that proceeds slowly or not at all and requires a large activation energy to the ligand substitution, where as complexes proceed quickly reached equilibrium with ligands are the Labile Complex (Reactive).
How do you know if a compound is inert or labile?
A compound in which metal-ligand bonds are easily broken is referred to as “labile”. A compound in which metal-ligand bonds are more difficult to break is referred to as “inert”.
