Three geometrical isomers are possible for .
Draw molecular structures of these three isomers.
Assertion (A): Linkage isomerism arises in coordination compounds containing ambidentate ligand.
Reason (R): Ambidentate ligand has two different donor atoms.
Define the following terms with a suitable example of each:
Polydentate ligand
Homoleptic complex
In coordination compounds, metals show two types of linkages, primary and secondary. Primary valencies are ionisable and are satisfied by negatively charged ions. Secondary valencies are non-ionisable and are satisfied by neutral or negative ions having lone pair of electrons. Primary valencies are non-directional while secondary valencies decide the shape of the complexes.
If PtCl2 ยท 2NH3 does not react with AgNO3, what will be its formula?
Write the structural shape of [Cr(NH3)6]3+.
Write the magnetic behaviour of [Cr(NH3)6]3+.
Write the hybrid orbitals involved in [Cr(NH3)6]3+.
Coordination compounds are widely present in the minerals, plant and animal worlds and are known to play many important functions in the area of analytical chemistry, metallurgy, biological systems and medicine. Alfred Werner's theory postulated the use of two types of linkages (primary and secondary), by a metal atom/ion in a coordination compound. He predicted the geometrical shapes of a large number of coordination entities using the property of isomerism. The Valence Bond Theory (VBT) explains the formation, magnetic behaviour and geometrical shapes of coordination compounds. It, however, fails to describe the optical properties of these compounds. The Crystal Field Theory (CFT) explains the effect of different crystal fields (provided by the ligands taken as point charges) on the degeneracy of d-orbital energies of the central metal atom/ion.
Give reasons why low spin tetrahedral complexes are not formed.
Give reasons why [Co(NH3)6]3+ is an inner orbital complex whereas [Ni(NH3)6]2+ is an outer orbital complex. [Atomic number : Co = 27, Ni = 28]
Write the hybridisation and magnetic characters of the following complexes:
[Fe(CN)6]4-
[CoF6]3-
[Ni(CO)4] [Atomic number: Fe = 26, Co = 27, Ni = 28]
What is the IUPAC name of [Co(NH3)5Cl]Cl2?
The oxidation state of Ni in [Ni(CO)4] is
Describe with an example of each, the role of coordination compounds in:
biological system
