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...

Observations. нь со скрипис 9. Build the cyclopentane ring and study the angle strain and torsional strain in the ring. Draw the structures to explain these factors. Cyclopentane actually assumes a slightly puckered "envelope" conformation that reduces the eclipsing and lowers the torsional strain. Convince yourself about this fact. Provide the relevant drawings. 10. Build the cyclohexane ring and study the angle strain and torsional strain. Build the chair and boat conformations and identify the axial and equatorial bonds.
