Verified step by step guidance

Understand the concept of constitutional isomers: Constitutional isomers are compounds that have the same molecular formula but differ in the connectivity of their atoms.

Identify the molecular formula of butane: Butane has the molecular formula C4H10.

Recognize the structure of butane: The typical structure of butane is a straight chain of four carbon atoms, each bonded to hydrogen atoms to satisfy the valency of carbon.

Consider alternative connectivity: To draw a constitutional isomer, rearrange the carbon atoms to form a different structure, such as a branched chain, while maintaining the same molecular formula.

Draw the isomer: One common constitutional isomer of butane is isobutane (or methylpropane), where three carbon atoms form a chain and the fourth carbon is attached as a branch to the middle carbon atom.
