Which of the following terms is not used for ionic compounds?
Correct answer: C. molecular formula
- A. Formula unit
- B. Empirical formula
- C. molecular formula
- D. Formula mass
Explanation
This term is not used for ionic compounds. Molecular formulas are specifically associated with covalent compounds, where discrete molecules exist. In ionic compounds, there are no discrete molecules; instead, there are repeating arrays of ions.Ionic compounds consist of ions rather than molecules. The terms associated with ionic compounds are:

About Fundamental Concepts of Chemistry
Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
