Question 12 of 22 > O Macmillan Learning Given the planar trisubstituted cyclohexane, fill in the missing substituents (with H or Cl) to complete the two possible cyclohexane chair conformations. Then, determine the more stable conformer. You might find it helpful to make a model of the cyclohexane to help visualize the chair conformations. CI H F □ H H H chair flip *4 = $x H H H H H H Answer Bank H H Br Chair 1 Br H F Cl Chair 2
It is easy to imagine a cyclohexane as a flat hexagon and a lot of the time we draw it that way. Looking at 1,3,5-triethylcyclohexane we cannot tell the stability of the molecule from looking at the flat 2D drawing. Explain why we need to look at the 3D configuration and what conformation (axial,equatorial) would each of the three ethyl groups be in for the most stable configuration.
