The chemical formula of butane is C4H10. It is a hydrocarbon with four carbon atoms and ten hydrogen atoms. The molecular structure of butane consists of a straight chain of four carbon atoms with single bonds between them, and each carbon atom is bonded to two hydrogen atoms.
The configuration of butane can be represented as follows:
CH3-CH2-CH2-CH3
In this structure, each carbon atom is tetrahedral in shape, with bond angles of approximately 109.5 degrees. The molecule is nonpolar and has a symmetrical shape.
Butane is a colorless, odorless gas at room temperature and pressure. It is commonly used as a fuel for lighters, stoves, and camping equipment.
