1. Build cyclohexane in ChemDraw. Copy and paste the structure into Chem3D. Then find the lowest-energy conformation. Record the total strain energy of this conformation from the "Untitled-1: Messages" window. Use the trackball to rotate the molecule to view it from different perspectives. Find the most informative view of this lowest-energy conformation. Start Microsoft Word and open a new Word document. Type your name and Chem 333L laboratory section at the top of the page. Then paste in the preferred view of the lowest-energy conformation of cyclohexane. Annotate this view with the total strain energy.

1. Build cyclohexane in ChemDraw. Copy and paste the structure into Chem3D. Then find
the lowest-energy conformation. Record the total strain energy of this conformation from
the "Untitled-1: Messages" window. Use the trackball to rotate the molecule to view it from
different perspectives. Find the most informative view of this lowest-energy conformation.
Start Microsoft Word and open a new Word document. Type your name and Chem 333L
laboratory section at the top of the page. Then paste in the preferred view of the lowest-energy
conformation of cyclohexane. Annotate this view with the total strain energy.
2. Repeat exercise 1 for methylcyclohexane, with the methyl group in an axial position. Then do
the same for methyleyclohexane with the methyl group in an equatorial position. Compare the
total strain energy values for both of the conformations. Paste these annotated views into your
Word document.
3. Repeat exercise 2 for t-butylcyclohexane, with the r-butyl group in an axial position. Then do
the same for t-butylcyclohexane with the t-butyl group in an equatorial position. Compare the
total strain energy values for the two conformations. Paste these annotated views into your
Word document.
4. Repeat exercise 1 for cis-1,2-dimethylcyclohexane. Determine the H-C-C-H dihedral angle
between the two methine protons, also. Record the calculated dihedral angle. Paste the annotated
view into your Word document. Include both the total strain energy and dihedral angle values.
5. Repeat exercise 4 for trans-1,2-dimethylcyclohexane. Paste the annotated view into your
Word document.
