Chapter 3, Problem 116E

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.
