Chapter 2 Quiz

1. (2 points each) Write a complete IUPAC name for each of the following compounds:
a)

trans-1-bromo-3-isopropylcyclopentane
OR
trans-1-bromo-3-(1-methylethyl)cyclopentane

---

b)

3-ethyl-1-fluoro-2,4-dimethylpentane

2. (3 points) Write the Newman diagrams for the three staggered conformations of 3,3-dimethylpentane, specifically looking down the C2-C3 bond. Select the most stable conformation.

3. (3 points) Write both chair conformations for trans-1-chloro-3-methylcyclohexane. Using the data table provided (textbook Table 2.4, page 77), predict the most stable and calculate delta G for the equilibrium.

The equilibrium will be favored to the right by delta G = - 1.22 kcal/mol .
