straight-chain hydrocarbon

A straight-chain hydrocarbon is an organic compound composed solely of carbon and hydrogen atoms linked in a continuous, unbranched chain. These compounds are known as alkanes and have the general molecular formula C_nH_{2n + 2}. In alkanes, all carbon-carbon and carbon-hydrogen bonds are single sigma bonds, making them chemically stable and less reactive. The simplest alkanes are methane (CH₄), ethane (C₂H₆), and propane (C₃H₈). As the number of carbon atoms increases, different structural arrangements, called isomers, become possible, leading to compounds with the same molecular formula but different physical properties, such as boiling points. Hydrocarbons are fundamental components of petroleum and natural gas and are crucial raw materials for various industrial products.12345678
