Coordinate Compounds Flashcards
Coordinate compounds
Those compounds in which metal atoms or ions are bonded to ions or neutral molecules by coordinate bond
The product written in [] is called __ and outside is __
Complex part; counter ion
Product when Cuso4 + nh3
[Cu(NH3)⁴]SO⁴
Product of NiCl² + 4nh3
[Ni(nh3)⁴]Cl
Ligands are
Charged ions or neutral molecules that can give 2 e’s to form coordinate bond
How many ions will form when h20 + [Co(nh3)⁴Cl²]Cl?
2, i.e [Co(nh3)⁴Cl²] & Cl
Which will ionise in solution, Double salt or coordinate compds?
Double salt
Monodentate/unidentate ligands
Ligands which are able to form only 1 coordinate hond
Examples of monodentrate
NH³,H2O,PH³,P(C⁶H⁵)³,CH³-NH²
charged ligands like hallides, OH, NO², NO³
Ambidentate ligands
Ligands that can form bonds in 2 ways by 2 atoms
Ambidentate ligands examples
A metal with NO², SCN
Bidentate ligands
Ligands which can form only 2 bonds
Ex of bidentate
NH²–CH²-CH²–NH² where N has 1 lone pair, oxalic acid,glycine
Coordination compounds of Mg, Fe & Co
Chlorophyll,haemoglobin & Vitamin B¹²
Applications of coordination compounds
Electroplating, textile dyeing & medicinal chemistry
Ex of double salts
Carnallite,KCl.MgCl2.6H2O,Mohr’s salt,potash alum
Central atoms are also called
Lewis acids
Number of ligating groups are called
Denticity of the ligand
Oxalic acid structure
HooC-CooH
Among amino acids, which one is optically inactive
Glycine ²HN-CH²-COOH since it is not chiral
Ex of hexadentate ligands
Ethylene diamine tetraacetate ion(EDTA⁴-), [Co(en)³]³+
