C4H10n

C4H10n refers to a class of organic compounds with the molecular formula C4H10. This formula indicates that the molecule consists of four carbon atoms and ten hydrogen atoms. The "n" typically denotes that the formula represents a general structure or a class of isomers. These compounds are known as butanes.

The primary isomers of C4H10 are n-butane and isobutane (also known as 2-methylpropane). n-butane is a straight-chain alkane where all four carbon atoms are linked in a continuous chain. Isobutane is a branched alkane, with three carbon atoms in a chain and one carbon atom attached as a branch to the central carbon. Both n-butane and isobutane are saturated hydrocarbons, meaning they contain only single bonds between carbon atoms and are fully saturated with hydrogen atoms.

These compounds are colorless and odorless gases at standard temperature and pressure. They are highly flammable and are commonly found as components of natural gas and liquefied petroleum gas (LPG). n-butane is often used as a fuel, a propellant in aerosol cans, and as a feedstock in the petrochemical industry for the production of other chemicals. Isobutane also finds use as a fuel and refrigerant, and it can be isomerized to n-butane. The properties and applications of C4H10n isomers are influenced by their specific molecular structure.
