COORDINATION COMPOUNDS
WERNER’S THEORY AND LIGANDS
Define the term coordination compound?
A coordination complex is the product of a lewis acid-base reaction, in which the neutral molecules or anions (or ligands) bond to the central metal atom by coordinate or covalent bond. And the compound having these coordination complex are called Coordination Compounds.
Define
(a) Homoleptic complex
(b) Heteroleptic complexes
with the help of one example of each.
Homoleptic and heteroleptic complexes in which a metal is bound to only one kind of donor group, e.g., [Co(NH3)6]3+, are known as homoleptic. Complexes in which a metal is bound to more than one kind of donor group, e.g., [Co(NH3)4Cl2]+, are known as heteroleptic.
What do you understand by ‘denticity of a ligand’ & its type?
The denticity of the ligand is defined as the number of pairs of electrons shared with the metal atom or ion. Ligands can be classified as monodentate and polydentate ligands depending upon the number of ligand donor atoms that attach to the metal atom or ion.
What is meant by unidentate ligands give there example & oxidation state?
Unidentate The negative ion or neutral molecule having only one donor atom is called unidentate ligand e.g
Is NH3 is an example of monodentate ligand?
Answer:Ammonia has lone pair of electrons that is shared with central metal atom or ions. NH3 is capable of sharing only one pair of electrons so it is an example of monodentate ligand.
