Q1
The central metal atom in a coordination compound is bonded to:
📝 SolutionIn coordination compounds, the central metal ion is surrounded by and bonded to ligands (ions or molecules that donate electron pairs).
Q2
A ligand is a species that donates:
📝 SolutionA ligand is an ion or molecule that donates a lone pair of electrons to the central metal to form a coordinate bond.
Q3
The number of ligand donor atoms bonded to the central metal is called the:
📝 SolutionThe coordination number is the number of donor atoms directly bonded to the central metal ion.
Q4
In the complex $[Cu(NH_3)_4]^{2+}$, the coordination number of copper is:
📝 SolutionThere are four ammonia ligands bonded to copper, so the coordination number is 4.
Q5
A ligand that binds through two donor atoms is called:
📝 SolutionA bidentate ligand has two donor atoms that both bond to the metal, e.g. ethylenediamine (en).
