Following the instructions for drawing the energy levels of the molecular orbitals for the compoundsshown in Figure 8.17, draw the energy levels of the molecular orbitals for the cycloheptatrienyl cation, thecycloheptatrienylanion, and the cyclopropenyl cation. For each compound, show the distribution of thep electrons. Which of the compounds are aromatic?
Reading, Writing and Doing Science 1 Learning Objectives As you work through this chapter you will learn how to: < identify and apply the elements of the scientific method. < distinguish between science and pseudoscience. < plan a scientific experiment. < identify quantitative relationships between two quantities. < graph quantitative data on an x-y scatter plot. < interpret straight line graphs. 1.1 The Language of Science Have you or a friend, when thinking about or discussing some situation, ever said “My theory is ...” In science sometimes commonly used words like theory have a very different meaning than what is usually associated with the term. In addition, there is often a
