Question

which of the following is an example of an ionic compound? view available hint(s) carbon dioxide oxygen water sodium chloride

Explanation:

To determine the ionic compound, we analyze each option:

• Carbon dioxide ($\ce{CO_2}$) is a covalent compound formed by non - metals (C and O) sharing electrons.
• Oxygen ($\ce{O_2}$) is a diatomic molecule of the same non - metal, held together by a covalent bond.
• Water ($\ce{H_2O}$) is a covalent compound where H and O share electrons.
• Sodium chloride ($\ce{NaCl}$) is formed from sodium (a metal) and chlorine (a non - metal). Sodium donates an electron to chlorine, forming $\ce{Na+}$ and $\ce{Cl-}$ ions, which are held together by ionic bonds, making it an ionic compound.

Answer:

D. sodium chloride
