Chapter 2.7, Problem 3RC

Interpretation Introduction

Interpretation: the name of the given formula of compound is to be identified from the given options.

Concept introduction:

Naming of ions:

Positive ions (cations) are named as metal name, example: aluminum for aluminum cation.

But, for the transition metals the ionic charge also included by roman numerals with the naming of compound. The polyatomic cation $N{H}_4{}^{+}$ is named as ammonium cation.

Negative ions (anions) are named by adding ‘ide’ to the stem of the nonmetal element from which the anion is formed, example: chloride, bromide, etc. in case of poly anions, the $oxoanions$ series is named by checking the number of oxygen atom is present in it. If the $oxoanion$ is having greater number of oxygen, then suffix will be ‘ate’. If the number of oxygen atom is less, then the suffix will be $‘ite’$ . And if the $oxoanion$ is having more than elements, then prefix will be added as ‘per’ with suffix ‘ate’ ions and ‘hypo’ with suffix $‘ite’$ of the $oxoanions$. The hydrogen containing $oxoanions$ is named by adding ‘hydrogen’ before the name of anion part.
