Hydrogen atoms in axial positions are shown in red while those in equatorial positions are in blue. You will need a molecular model kit to aid you in completing the exercises. Here we have a model of the cyclohexane molecule and it looks like its a flat hexagon from this perspective but it isnt really if we turn it to the side we can see this is not a planar molecule this is called the chair conformation of cyclohexane and if we stare down these two carbons well be able to see the chair conformation from a Newman projection viewpoint so now you can see that we have staggered hydrogens here we have a picture of the chair conformation.
Every carbon on the chair conformation has 1 substituent axial.
Then flip the model into the other chair conformation. This is a model of the chair conformation of cyclohexane. However with so much strain on the bonds it prefers to adopt a chair conformation. More than 99 of the molecules are in a chair conformation at any given time. Then flip the model into the other chair conformation.
