Covalently bonded molecules have strong bonds within the molecule due to the sharing of electrons between atoms. In covalent bonds, atoms share electrons to achieve a more stable electron configuration, often resembling that of noble gases. The shared electrons create a force of attraction between the positively charged atomic nuclei and the negatively charged electrons, resulting in a strong and directional bond. The strength of covalent bonds is attributed to the close proximity of shared electrons to both nuclei, creating a stable arrangement and resisting separation. This sharing of electrons imparts stability to the molecule, contributing to the overall strength of covalent bonds.
Intermolecular forces are attractive or repulsive forces between molecules. In covalent compounds, intermolecular forces, such as London dispersion forces, dipole-dipole interactions, and hydrogen bonding, are relatively weak compared to the strong covalent bonds holding atoms within a molecule.

Intermolecular forces are attractive or repulsive forces between molecules. In covalent compounds, intermolecular forces, such as London dispersion forces, dipole-dipole interactions, and hydrogen bonding, are relatively weak compared to the strong covalent bonds holding atoms within a molecule. Covalent compounds consist of molecules with discrete entities, and the intermolecular forces arise from interactions between these molecules. The weakness of these forces is due to the separation between molecules and the fact that they result from temporary or induced dipoles, partial charges, or hydrogen bonding rather than the direct sharing or transfer of electrons as seen in covalent bonds within a molecule.
Covalent compounds generally have low melting and boiling points due to the weak intermolecular forces between molecules. In these compounds, atoms are held together by strong covalent bonds within molecules, but the interactions between molecules are relatively weak. Intermolecular forces, such asRead more
Covalent compounds generally have low melting and boiling points due to the weak intermolecular forces between molecules. In these compounds, atoms are held together by strong covalent bonds within molecules, but the interactions between molecules are relatively weak. Intermolecular forces, such as London dispersion forces, dipole-dipole interactions, or hydrogen bonding, are responsible for holding molecules together. As these forces are weaker than the covalent bonds within molecules, less energy is required to overcome them, resulting in lower melting and boiling points. This contrasts with ionic or metallic compounds where stronger intermolecular forces contribute to higher melting and boiling points.
Covalent compounds are generally poor conductors of electricity because they lack free-moving charged particles. In covalent compounds, electrons are shared between atoms to form molecules, and the electrons are localized within the bonds. Unlike ionic or metallic compounds where charged particles (Read more
Covalent compounds are generally poor conductors of electricity because they lack free-moving charged particles. In covalent compounds, electrons are shared between atoms to form molecules, and the electrons are localized within the bonds. Unlike ionic or metallic compounds where charged particles (ions or delocalized electrons) can move freely, covalent compounds do not have mobile charges. As a result, they do not conduct electricity well in either solid or liquid states. Exceptions include certain covalent compounds that ionize or dissociate in solution, forming ions that can conduct electricity, but this behavior is less common compared to ionic or metallic substances.
The vast diversity of carbon compounds arises from carbon's unique ability to form stable, strong covalent bonds with itself and other elements, leading to an extensive variety of molecular structures. Carbon can bond with other carbon atoms, creating long chains, branches, and rings. Additionally,Read more
The vast diversity of carbon compounds arises from carbon’s unique ability to form stable, strong covalent bonds with itself and other elements, leading to an extensive variety of molecular structures. Carbon can bond with other carbon atoms, creating long chains, branches, and rings. Additionally, it readily forms bonds with diverse elements like hydrogen, oxygen, nitrogen, and more. This versatility, coupled with the possibility of isomerism and the ability to undergo multiple types of reactions, contributes to the enormous number and diversity of carbon compounds. The field of organic chemistry explores this richness, making carbon the basis of life’s molecular complexity.
