Substituted Cyclohexanes :
cis-1,2-dimethylcyclohexane

This tutorial shows the relationships between the two-dimensional Newman and chair projections for cyclohexane and and their three-dimensional chair structures. The arrow in each chair figure shows the perspective from which the Newman projection is drawn. Use the three-dimensional model to match perspectives with both the chair conformation and the Newman projection.
Red = methyl carbons, Grey = all other carbons, Cyan = hydrogen
