1. Consider the isomers of C5H10.
a. Draw and name all the structural isomers of C5H10.
b. Give an example of a set of geometric isomers of C5H10(i.e. cis and trans).
2. Consider the molecule 2-methylhexane.
a. Sketch the line drawing (skeletal structure) below.
b. Draw the most stable Newman projection(s) about the C3-C4 bond.
c. Draw the least stable Newman projection(s) about the C3-C4 bond.
d. How many of the C-C bonds have equally stable staggered conformers?
3. Explain why dioctylether has a higher boiling point than ethanol.
7. Draw and rank the relative stability of the four chair conformations 1-ethyl-2-propylcyclohexane. Remember two of these conformations will be the cis isomer and two will be the trans isomer.
