Answer to Problem 84E

The naming of HC2H3O2 is acetic acid.

Explanation of Solution

To determine: The  naming of HC2H3O2

The naming of HC2H3O2 is acetic acid.

Rules for 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. Monatomic anions are named with the ending -ide.
  • Roman numerals are used to show the oxidation state because some elements exhibit more than one oxidation state.
  • When oxygen is not present in anion, then acids is named by using “hydro-” 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.

In the acidic compound HC2H3O2 the cation is hydrogen (H+) and anion is acetate (C2H3O2)

Hence, the name of given compound is acetic acid.
