C13H28

C13H28 is the molecular formula for thirteen carbon atoms and twenty-eight hydrogen atoms. This formula represents a saturated hydrocarbon, meaning it consists only of carbon and hydrogen atoms connected by single bonds. Molecules with this formula are alkanes, which are generally unreactive and form the basis of many organic compounds. Specifically, C13H28 can represent several different structural isomers, meaning the atoms can be arranged in various ways while maintaining the same overall formula. The straight-chain isomer is known as n-tridecane. Other isomers will have branched carbon chains. These isomers, collectively referred to as tridecanes, are typically found in petroleum and are often components of fuels and lubricants. Their physical properties, such as boiling point and melting point, vary depending on the specific isomer. Generally, they are nonpolar, insoluble in water, and soluble in organic solvents. Due to their saturated nature, they undergo combustion reactions when exposed to sufficient oxygen, producing carbon dioxide and water.
