Exam # 1 Study Guide Organic Chemistry: Study Guide (Exam I)Lecture I: (January 12, 2015)1. What are the five common functional groups? Write out their line formula.2. Name the five alkanes. Write out the structural and line angle formula for each.Before doing any other problems, It is good to familiarize yourself with Table 3.1 (pg. 66), Table 3.2 (pg. 69), and table 3.3(pg 70) in your book. The rules of the IUPAC system are important to know also.3. Write IUPAC names for these alkanes.4. Write line formulas for the following alkanes.(a) 2,2,4-Trimethylhexane(b) 2,2 Dimethylpropane(c) 4- Isopropylcyclopentane (d) 2-ethyl-propylcyclohexane5.
