Summary Introduction

To determine:

The two conformers of butane using skeletal structures.

Introduction:

Skeletal structure shows the bonds between the carbon atoms in the form of lines in two dimensions. The connection between the two carbons is indicated by a line. The number of $\text{C-H}$ bonds to any carbon atoms is equal to four minus the bonds formed by the carbon as carbon always involved four bonds.

Conformational isomers are the isomers that can be interconverted when there is a rotation about the single bonds. These isomers are the form of stereoisomers having the same connectivity but differ in the spatial arrangements. For example, gauche, eclipsed are the conformational isomers of one another.
