Question

Butane is used as a fuel in disposable lighters. Write the Lewis structure for each isomer of butane.

Short answer

Butane has just two structural isomers: \({\rm{2}}\)-methylpropane and isobutane.

Step-by-step solution

Lewis’sstructure:

A Lewis structure is a molecule’s structural depiction in which dots indicate electron locations surrounding the atoms and lines or dot pairs represent covalent interactions. The objective of creating a Lewis dot structure is to aid detect chemical bonds formation by identifying lone electrons in molecules

Determining the Lewis structure for each isomer of butane

Butane is an alkane composed of four carbon atoms arranged in a straight chain.

Alkane and\({\rm{2}}\)-methylpropane or isobutane are two chemicals that can be made out of those four carbon atoms.

It's the only alternative since structural isomers have the same chemical formula but different structural properties.

As a result, the number of single bonds remains constant, and hybridization remains unchanged.
