Chapter 12, Problem 94A

Interpretation Introduction

Interpretation: A compound that can have both ionic and covalent bonds is to be explained.

Concept Introduction: Atoms that are not metals establish covalent bonds by sharing electron pairs. Electrostatic interaction between ions in a compound with opposite charges forms an ionic bond:

Answer to Problem 94A

A compound can have both ionic and covalent bonds.

Explanation of Solution

Both ionic and covalent bonds are present in certain compounds. Polycations are present in these compounds. Most of these compounds are made up of nonmetal, metal, and hydrogen atoms. However, some examples involve a metal covalently bonded to a nonmetal through an ionic bond. Sodium nitrate, ammonium sulfide, potassium, and sulfate can exhibit both covalent and ionic bonds.

Conclusion

A compound can have both ionic and covalent bonds.
