6. Build the cyclobutane ring and study the angle strain and torsional strain. Draw the structures to explain these factors. 7. The conformation of cyclobutane is slightly folded. Folding gives partial relief from the eclipsing of bonds, as shown in the Newman projection. Compare this actual structure with the hypothetical planar structure. Draw the relevant structures. 8. trans-1,2-Dimethylcyclobutane is more stable than cis-1,2-dimethylcyclobutane, but cis-1,3- dimethylcyclobutane is more stable than trans-1,3-dimethylcyclobutane. Use the molecular models to find the reasons for...

Cyclohexane Conformations Put your model of cis-1,3-dichlorocyclohexane into a chair conformation. Sometimes the easiest way to do this is by adjusting it to make the axial bonds alternate up and down. Now convert it to the other chair structure, asking the instructor for help if needed. Is the second conformation still cis or is it trans? Are the two conformations the same or are they different? Draw chair structures of both conformations making sure to...
