The molecular formula C4H10 corresponds to the chemical formula for butane, which is an alkane with four carbon atoms. In the case of C4H10, there are two different structural isomers possible:
n-Butane (normal butane): It has a straight chain of four carbon atoms with ten hydrogen atoms attached. The structure can be represented as CH3-CH2-CH2-CH3.
Isobutane (2-methylpropane): It consists of a branched chain with a methyl group (CH3) attached to the second carbon atom. The structure can be represented as (CH3)3-CH.
These two isomers, n-butane and isobutane, are the only ones that satisfy the molecular formula C4H10.
