Aliphatic compounds are organic molecules composed of carbon and hydrogen, arranged in straight chains, branched chains, or non-aromatic rings. They are classified into alkanes, alkenes, and alkynes based on their bonding types. Unlike aromatic compounds, aliphatic hydrocarbons do not contain benzene rings. Examples include methane, propane, and butene. These compounds are widely used in fuels, lubricants, and industrial chemicals..
