Chemists work with so many hydrocarbons that they abbreviate the structures with lines and vertices. Hexane, for instance, can be drawn as follows:

In this drawing, each end or vertex is a carbon atom, and it is assumed that sufficient hydrogens are added to each carbon to give each carbon 4 connections: CH₃CH₂CH₂CH₂CH₂CH₃. Moreover, the zig-zag nature of the drawing provides information about the relative angles of the carbons to each other. What, then, is the systematic name of the following compound?
