Difference Between Inert and Labile Complexes

The key difference between inert and labile complexes is that inert complexes undergo slow substitution, whereas labile complexes undergo rapid substitution. ... Labile complexes, on the other hand, are thermodynamically unstable, and they have a very small activation energy barrier.

What are labile and inert complexes?

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 are labile and inert complexes examples?

[Sc(OH₂)₆]Cl₃ + 6 NaSCN —> Na₃[Sc(SCN)₆] + 3 NaCl (very fast!) Lability refers to how easily metal-ligand bonds are broken. 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".

What are labile and inert complexes give two examples?

Metal complexes with d0, d1, d2, d10 are labile in nature and undergo fast 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 following ion is most labile?

Cr3+ ion is the most stable in aqueous solution on account of maximum crystal field stabilization energy.

What does the word labile mean?

labile \LAY-byle\ adjective. 1 : readily or continually undergoing chemical, physical, or biological change or breakdown : unstable. 2 : readily open to change.

What ion is kinetically inert?

12.4 The [Fe(CN)6]4– ion is a low-spin d6 complex, with a maximum LFSE of –2.4 ∆o. It is a notably kinetically inert complex, hence its low reactivity towards ligand substitution that would release the potentially toxic cyanide.

What is meant by kinetically inert?

Kinetically inert means that the activation energy required for product formation is very high. Be and Mg have very less reduction potential E⁰ compared to other members of the same group. This indicates that they are less electropositive, hence do not reacts with cold water.

How do you determine the stability of a complex?

The most important characteristics of the central atom, determining the stability of the complex compound, are the degree of oxidation (charge on the central ion in the case of ionic complexes), the dimensions, and the electronic structure.

What do you mean by stability of metal complex?

In other words, thermodynamic stability of complexes is the measure of tendency of a metal ion to selectively form a specific metal complex and is directly related to the metal-ligand bond energies. The thermodynamic stability of complexes is represented by formation constant.

What is chelate effect?

Answer: Lewis base which donates two lone pairs of electrons to the central metal atom is known as bidentate ligands. They are referred to as chelating ligands. ... Complexes containing chelate rings are more stable than complex without rings. This is called the chelate effect.

What is trance effect?

In inorganic chemistry, the trans effect is the labilization (making more reactive) of ligands that are trans to certain other ligands, which can thus be regarded as trans-directing ligands. ... The discovery of the trans effect is attributed to Ilya Ilich Chernyaev, who recognized it and gave it a name in 1926.

What is meant by spectrochemical series?

A spectrochemical series is a list of ligands ordered on ligand strength and a list of metal ions based on oxidation number, group and its identity.
