Verified step by step guidance

Understand the difference between ionic and covalent compounds: Ionic compounds are formed by the transfer of electrons between metals and nonmetals, resulting in positive and negative ions held together by electrostatic forces. Covalent compounds involve the sharing of electrons between nonmetals.

Examine each formula to identify the types of elements involved: H_2O (water) contains hydrogen and oxygen, both nonmetals; CO_2 (carbon dioxide) contains carbon and oxygen, both nonmetals; C_6H_{12}O_6 (glucose) contains carbon, hydrogen, and oxygen, all nonmetals.

Recognize that NaCl (sodium chloride) consists of sodium (a metal) and chlorine (a nonmetal), which typically form an ionic bond due to electron transfer from sodium to chlorine.

Conclude that among the given options, only NaCl represents an ionic compound because it contains a metal and a nonmetal forming ions, while the others are molecular (covalent) compounds.

Summarize that identifying ionic compounds involves looking for combinations of metals and nonmetals, which form ions, unlike covalent compounds formed by nonmetals only.
