What is Covalent Compounds?
Covalent compounds are substances whose atoms are held together by covalent bonds rather than ionic bonds. They consist of discrete molecules (molecular compounds) or extended covalent networks (giant covalent structures such as diamond and silicon dioxide). Molecular covalent compounds typically have lower melting points than ionic compounds and are often soluble in non-polar solvents.

Frequently Asked Questions
Covalent compounds are substances whose atoms are held together by covalent bonds rather than ionic bonds. They consist of discrete molecules (molecular compounds) or extended covalent networks (giant covalent structures such as diamond and silicon dioxide). Molecular covalent compounds typically have lower melting points than ionic compounds and are often soluble in non-polar solvents.
Covalent compounds are the basis of all organic chemistry and most biochemistry. They include water, carbon dioxide, organic solvents, pharmaceuticals, polymers, and virtually all biological molecules (DNA, proteins, lipids). Industrial organic chemicals (ethylene, benzene, acetylene) are covalent.
Covalent compounds include some of the most toxic substances known (dioxins, nerve agents, HCN). Volatility of many covalent compounds creates inhalation hazards. Flammable organic solvents are common laboratory and industrial hazards. Always consult SDS before handling.
