The name of the oxyanions and acid has to be given. Concept introduction: The anion which contains oxygen is called oxy-anions. While naming covalent compound, the name of the cation is written first, followed by the name of the anion. Generally, the cation present is a metal or a polyatomic cation, whereas the anion is a non-metal. Rules for naming binary compound: In naming of binary compound, the name of cation comes first which is the name of element. Anion is named second which is also the name of element. When there are only two members in a compound then anion having at most two oxygen ends in –ite, and the anion having more than two oxygen ends in –ate. If more than two oxyanion is present in compound then “hypo-” (less than) and “per-” (more than) is used in prefix. If the name of anions ends in “ate-” then acid name ends in –ic or –ric. If the name of anion ends in “-ite”, then the name of acid ends in –ous.

Interpretation Introduction

Interpretation:

The name of the oxyanions and acid has to be given.

Concept introduction:

The anion which contains oxygen is called oxy-anions. While naming covalent compound, the name of the cation is written first, followed by the name of the anion. Generally, the cation present is a metal or a polyatomic cation, whereas the anion is a non-metal.

Rules for naming binary compound:

In naming of binary compound, the name of cation comes first which is the name of element. Anion is named second which is also the name of element.

When there are only two members in a compound then anion having at most two oxygen ends in –ite, and the anion having more than two oxygen ends in –ate.

If more than two oxyanion is present in compound then “hypo-” (less than) and “per-” (more than) is used in prefix.

If the name of anions ends in “ate-” then acid name ends in –ic or –ric.

If the name of anion ends in “-ite”, then the name of acid ends in –ous.
