Molecular compounds are chemical compounds that take the form of discrete molecules like water $$\left( \ce{H_2O} \right)$$ and carbon dioxide $$\left( \ce{CO_2} \right)$$. These compounds are very different from ionic compounds like sodium chloride $$\left( \ce{NaCl} \right)$$, which are formed when metal atoms lose one or more of their electrons to nonmetal atoms and the resulting ions are mutually attracted to each other.

• 3.1: Molecular Compounds
Molecular compounds are chemical compounds that take the form of discrete molecules. These compounds are very different from ionic compounds like sodium chloride (NaCl) . Ionic compounds are formed when metal atoms lose one or more of their electrons to nonmetal atoms. Rather than forming ions, the atoms of a molecule share their valence electrons in such a way that a bond forms between pairs of atoms.
• 3.2: Straight-Chain Alkanes
A hydrocarbon is an organic compound that is made up of only carbon and hydrogen. A hydrocarbon is the simplest kind of organic molecule and is the basis for all other more complex organic compounds.
