What is a binary molecular compound?

A binary molecular compound is a type of compound that is composed of two nonmetals. The atoms in these compounds form covalent bonds by sharing electrons to satisfy the octet rule. Binary molecular compounds have molecular formulas that indicate the number and type of atoms present in each molecule. These formulas are written using subscripts to indicate the number of atoms of each element present.

Examples of binary molecular compounds include water (H₂O), carbon dioxide (CO₂), methane (CH₄), and ammonia (NH₃). These compounds generally have low melting and boiling points, are typically gases or liquids at room temperature, and do not conduct electricity in their pure state. The properties of binary molecular compounds are determined by the strength of the covalent bonds between the atoms, the polarity of the molecule, and the size and shape of the molecules.
