Q1: Define coordination compounds. What are ligands and coordination number?
Coordination Compound:
A compound formed by combination of a central metal atom/ion with a certain number of anions or neutral molecules (called ligands) surrounding it.
General formula: [M(L)_n]^(m+/-)
where M = central metal, L = ligand, n = coordination number, m = charge
Example: [Cu(NH₃)₄]²⁺,...
Q2: Explain the crystal field theory and its application to octahedral complexes.
Crystal Field Theory (CFT):
Theory that explains the structure, color, and magnetic properties of coordination complexes based on electrostatic interactions between the central metal ion and the surrounding ligands.
Basic Assumption:
Ligands are treated as point charges or dipoles that create an el...
Q3: Write the IUPAC nomenclature rules for coordination compounds with examples.
IUPAC Nomenclature of Coordination Compounds:
General Rules (in order):
1. NAME THE CATION FIRST, then the anion
2. In the coordination sphere:
- Name ligands in alphabetical order
- Prefix numbers: mono-, di-, tri-, tetra-, penta-, hexa-, hepta-, octa-
- Use Greek prefixes regardless of...
