Basic Concepts 1.Q:What is a coordination compound ?      A:A compound containing a central metal atom/ion bonded to ligands via coordinate bonds . 2. Q: What is a ligand ?      A: An ion or molecule that donates a lone pair of electrons to the central metal atom/ion. 3. Q:What is coordination number ?      A:The number of ligand donor atoms directly bonded to the central metal ion. 4. Q:What are monodentate ligands ?      A:Ligands that donate only one pair of electrons (e.g., NH₃, H₂O, Cl⁻). 5. Q:Give an example of a polydentate ligand .      A: Ethylenediamine (en), Oxalate (C₂O₄²⁻). 6. Q:What is a chelating ligand ?      A: A ligand that forms two or more coordinate bonds with the same central metal ion. 7. Q:What is the oxidation number of Co in [Co(NH₃)₆]Cl₃?      A: +3. 8. Q:What is the difference between inner and outer orbital complexes?...
