What are molecular covalent compounds?
Molecular covalent compounds, also known as molecular compounds, are chemical compounds that are formed when atoms share electrons to achieve a stable electron configuration. These compounds are typically composed of non-metals and are held together by covalent bonds, which are formed when two atoms share one or more pairs of electrons. Examples of molecular covalent compounds include water (H2O), carbon dioxide (CO2), and methane (CH4).
Molecular covalent compounds are important because they form the basis of many of the materials that we use in everyday life, such as plastics, fuels, and pharmaceuticals. They are also essential for biological processes, such as the formation of proteins and DNA.
The study of molecular covalent compounds is a branch of chemistry known as molecular chemistry. Molecular chemistry is concerned with the structure, properties, and reactivity of molecular compounds.

Definition
This definition is essential to understanding molecular covalent compounds because it explains how these compounds are formed. Molecular covalent compounds are formed when atoms share electrons in order to achieve a stable electron configuration. This sharing of electrons creates a covalent bond between the atoms. The number of electrons that are shared determines the type of covalent bond that is formed. For example, a single bond is formed when two atoms share one pair of electrons, a double bond is formed when two atoms share two pairs of electrons, and a triple bond is formed when two atoms share three pairs of electrons.
Molecular covalent compounds are important because they form the basis of many of the materials that we use in everyday life. For example, water, carbon dioxide, and methane are all molecular covalent compounds. These compounds are essential for life and for the functioning of the world around us.

Properties
The properties of molecular covalent compounds are directly related to their structure and bonding. Because molecular covalent compounds are formed by the sharing of electrons between atoms, they do not have free electrons that can move and conduct electricity. This makes them non-polar and poor conductors of electricity.
The strength of the covalent bonds between atoms also affects the physical properties of molecular covalent compounds. Covalent bonds are typically strong, which means that molecular covalent compounds are not easily broken apart. This contributes to their relatively high melting and boiling points. However, the strength of the covalent bonds also means that molecular covalent compounds are not very flexible or malleable.
The properties of molecular covalent compounds make them well-suited for a variety of applications. For example, their non-polar nature makes them good insulators, and their low melting and boiling points make them useful as solvents. Molecular covalent compounds are also used in a variety of industrial processes, such as the production of plastics and pharmaceuticals.
Understanding the properties of molecular covalent compounds is important for understanding their behavior and applications. By understanding these properties, we can better understand the world around us and the materials that we use.
