20 Questions
Which ligand classification is based on the number of donor atoms present?
Monodentate, bidentate, and tridentate
Which of the following is an example of a bidentate ligand?

Why do metal carbonyls effectively obey the EAN rule?
Because they exist in a zero oxidation state
What is the effective atomic number (EAN) of Co in the compound Co(CO)₄?
72
What are addition or molecular compounds?
Compounds formed by mixing simple salts in molecular proportions resulting in new crystalline compounds
What is the effective atomic number (EAN) of V in the compound V(CO)₆?
35
What is the main difference between double salts and complex salts?
Double salts break down into their constituents when dissolved in water, while complex salts retain their identity even in solution
What is the role of ligands in coordination compounds?
Ligands form coordinate bonds with the central metal atom or ion
Which type of compound retains its identity even in solution and has properties different from those of its constituents?
Complex salts
In modern usage, how is the complex ion shown which behaves as a single unit?
Enclosed in square brackets, e.g. [Fe(CN)]
What prefixes are used for indicating multiple ligands in names like ethylenediamine and dipyridyl?
di, tri, tetra
What prefixes are used for complicated ligands like ethylenediamine and dipyridyl, which already have the prefixes di, tri in their names?
bis, tris, tetrakis
Which type of valency is equal to the coordination number of the metal in coordination compounds?
Secondary valency
Which theory postulates that metals in coordination compounds possess two types of valency: primary and secondary valency?
Werner's theory
What type of species satisfies the primary valency in a coordination compound according to Werner's theory?
Anions
How are simple salts named?
Cation followed by anion
What is the naming order for complex ions?
Ligands, central metal ion
How are negative ligands named?
Ends in -O
What is the naming convention for neutral ligands?
Use of special names like aqua, ammine, carbonyl
How are simple ligands like chloride (Cl⁻) and cyanide (CN⁻) named?
Named as the molecules
