(a)
Interpretation:
The given compound has to be named.
Concept Introduction:
The nomenclature of inorganic compounds involves following rules:
- The prefixes on each atom indicate the number of those atoms in the compound.
- The number written on the subscript of the anion is numerically equal to the charge on the cation and vice versa.
- Subscripts are discarded when the numerical charge on cation and anion are equal.
- When a metal has more than one positive oxidation state, its lowest oxidation number has name of the metal ion ending with ‘ous’ and highest oxidation number has name of the metal ion ending with ‘ic’. This rule is applicable when oxidation number of metal is not more than three.
- If a metal ion has multiple number of oxidation states more than three, then Roman numeral has to be used within square brackets to indicate the oxidation number of metal ion.
- Nomenclature of binary acids and oxoacids are not similar. Binary acids are named based on the non-metal atom present in them. Oxoacids are named on the basis of polyatomic anion present in them.
