Interpretation:
The name of given binary compound CaF2is to be written.
Concept introduction:
To name a compound, certain rules are followed. The given compounds are binary compounds.
Binary compounds are of three types:
- Type-I: Compound in which a metal forms ionic bond with a non-metal and the metal can form only one type of ions.
- Type-II: Compound in which a metal forms ionic bond with a non-metal and the metal can form more than one type of ions.
- Type-III: Compound in which a non-metal forms bond with a non-metal.
Rules for naming these compounds:
Type-I:
- Name of metal cation is written as name of element.
- Name of anion is written using root name and adding ‘ide’ to it.
- Writing these names in the same sequence gives the name of compound.
Type-II:
