To Choose: The correct option.

Answer to Problem 10STP

The correct option is (B).

Explanation of Solution

Introduction:

Nomenclature of molecules or compounds is a way through which it is easier to remember the name. It is a scientific way to denote compounds in a particular way.

Calculation:

Compounds consists of positive and negative ions respectively. In the compound ${\text{KC}}_{\text{2}}{\text{H}}_{\text{3}}{\text{O}}_{\text{2}}$ , one potassium ion is positively charged and acetate ion is a negatively charged ion. The compound can be written as ${\text{CH}}_{\text{3}}\text{COOK}$ .

The name of the positive part of the compound is written first followed by a negative part. Thus, the name of the compound is potassium acetate, and the options (A),(C) and (D) are wrong.

Conclusion:

Hence, the name of ${\text{KC}}_{\text{2}}{\text{H}}_{\text{3}}{\text{O}}_{\text{2}}$ is potassium acetate.
