What is a coordination compound?
Answer
A coordination compound is a molecular or addition compound in which a central metal atom or ion is permanently attached to ligands. The ligands donate electron pairs to the metal through coordinate b…
How is a coordination compound different from a double salt?
Answer
Double salts exist in the solid state but dissociate completely into constituent ions in water. Coordination compounds retain their identity in aqueous solution and show properties different from thei…
Why does K4[Fe(CN)6] behave as a coordination compound in water?
Answer
K4[Fe(CN)6] dissociates as K4[Fe(CN)6] ⇌ 4K+(aq) + [Fe(CN)6]4-(aq). The complex ion [Fe(CN)6]4- remains intact in solution and does not break into Fe2+ and CN- ions. Therefore, the compound retains it…
What is a ligand? Give two examples.
Answer
A ligand is an atom, ion, or molecule that donates at least one pair of electrons to a central metal atom or ion. Examples: NH3, CN-, H2O, CO.
What is coordination number?
Answer
The coordination number is the maximum number of ligands that can be attached to a central metal atom or ion. It commonly has values 4 or 6, but can vary from 2 to 10. Example: coordination number of …
How does coordination number decide geometry?
Answer
A central metal with coordination number 6 usually forms an octahedral complex. A central metal with coordination number 4 usually forms a tetrahedral or square planar complex. Example: [Co(NH3)6]3+ i…
What are primary valency and secondary valency in Werner's theory?
Answer
Primary valency is ionisable and corresponds to oxidation state. It is satisfied by negative ions. Secondary valency is non-ionisable and corresponds to coordination number. It is satisfied by negativ…
Why was octahedral geometry accepted for six-coordinate complexes?
Answer
Werner isolated only two isomers for six-coordinate compounds, and this is possible only for octahedral structures. Six-coordinate planar hexagon or trigonal prism arrangements would give three isomer…
