Solution: Which of the following compounds contains both ionic and covalent bonds?(A) HCl(B) NaCl(C) H2O(D) LiOH(E) CO2

Problem

Which of the following compounds contains both ionic and covalent bonds?

(A) HCl

(B) NaCl

(C) H2O

(D) LiOH

(E) CO2

Solution

We’re being asked to identify which of the given compounds contains both ionic and covalent bonds. Let’s first differentiate a covalent bond and an ionic bond.


Covalent or Molecular Compound

▪ composed of more than one nonmetal together
▪ nonmetal + nonmetal = covalent bond

Ionic Compound

▪ composed of a positive ion called a cation connected to a negative ion called an anion.
positive ions (cations) are usually metals and negative ions (anion) are usually nonmetals

metal + nonmetal = ionic bond

▪ cations and anions can also be polyatomic ions (example: NH4+, C­H3COO-, SO42-)


Now let’s identify which of the given compounds contains both ionic and covalent bonds:
