CHEM 162C Spring 2006 Topics for Midterm Exam 1 Goal: Get yourself prepared to be able to solve problems and answer multiple-choice and true-false questions concerning the following topics from Chapters 14 and 15 of the course textbook. Useful hints: Practice by independently solving the problems given in the textbook, homework, lectures, and quizzes. Although the problems on the test are very similar to those covered in the course and textbook, they may be formulated differently. You have to understand what you are doing to solve them successfully at the test. Each midterm exam contributes 15% to your total score in the course. Chapter 14.1. Hybridization types: Assign hybridization in various polyatomic molecules based on complete or incomplete structure formulas and/or Lewis structures. Chapter 14.2-14.4: Molecular orbital model: Draw and assign MO diagrams for homo and heteronuclear diatomic molecules; calculate bond orders; estimate magnetic properties, rank and/or estimate bond dissociation energies. Chapter 14.5: Sort out sigma and pi orbitals in polyatomic molecules. Chapter 14.7-14.8: Electronic Spectroscopy: calculate and/or convert wavelength and frequency. Draw, complete, or assign diagrams for electron excitation to antibonding orbitals and their relation to electronic spectra. Chapter 14.9: Vibrational spectroscopy: Assign vibrational modes (degrees of freedom) and distinguish stretching and bending modes in polyatomic molecules; calculate the effects on vibrational frequencies of bond force constants and atomic mass; be able to interconvert wavenumbers, energies, and frequencies. Chapter 15.1. : Reaction rates: Know, understand, and be able to use definitions and units. Chapter 15.2-15.5: Assign rate laws, (zeroth, first, and second order reactions), calculate half-lives, use differential and integral forms of rate laws to calculate reaction time and/or concentrations of reactants and products. Chapter 15.6-15.7: Be able to assign reaction mechanisms, use steady state approximation for determining rate laws. Chapter 15.8: Use the Arrhenius equation to determine the dependence of rate constants on temperature and calculate rate constants, activation energies, and frequency factors.
