1. Draw the different conformations of cyclohexane and indicate which conformer is more stable and explain the reason why it is more stable. 2. Draw the saddle conformation of cyclohexane and indicate the axial and equatorial positions of the hydrogen atoms. 3. Identify the chiral carbon with an asterisk in the following molecule. Say how many stereoisomers you can have. CH3CH(OH)CH(Br)CH3

9. Draw two different chair conformations of cyclohexanol, showing all hydropen atoms. Identify each position as axial or equatorial 10. 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...

Cyclohexane: 1.Make a boat conformation. 2.Then a chair conformation In which case are the C-H bonds on neighboring carbons eclipsing the most? 3. In which case do the H atoms on C1 and C4 approach each other most closely? 4. Based on what you saw above, which will be the most stable conformation of cyclohexane? Draw both conformations

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...

Question 1: Make models of cyclobutane and cyclohexane and then carefully draw these models a) Does anything become apparent to you when you are making one model compared to the other? b) Describe the shapes of these molecules and indicate what types of strain might be present in each. c) Are either of your models "flat" like a hexagon or a square? Question 2: Make a model of cyclopentane. a) Is your model flat like a pentagon? b) Why or...
