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...

Draw the most stable chair conformation of the following molecules, and estimate the amount of strain in each: (a) trans-1-Chloro-3-methylcyclohexane (b) cis-1-Ethyl-2-methylcyclohexane (c) cis-1-Bromo-4-ethylcyclohexane (d) cis-1-tert-Butylcyclohexane 11. Which isomer is more stable, cis-decalin or trans-decalin? Explain. 12. Glucose exists in two forms having a 36:64 ratio at equilibrium. Draw a skeletal structure of each, describe the difference between them and...
