Dr. Jim Bloxton CHEM 1022 Spring 2008 OPTIONAL PRACTICE MIDTERM EXAM I ANSWER KEY Note: This is optional practice material for Midterm Exam I for chapters 10, 11, 12, 13 & 15. These are sample questions that may or may not be used on a midterm or final exam. Other questions that are not found on this sample midterm exam will be on the actual midterm exam. Learn the basic principles and then be prepared to apply the principles to problems that you have not seen before. This includes all material that was covered or contained in the Chem 1022 lecture text, lecture notes, lecture handouts, study guides, recitation notes, and recitation handouts. It is very important to review all practice and actual lecture quizzes, midterms, study guides and homework materials. Several other practice midterm exams could have been generated from these materials that would look very different from this practice midterm exam. Note: It is very important to remember that Chemistry is a cumulative topic and that the material that was covered in previous chapters needs to be reviewed as this material will continue to reappear in concepts that are needed to solve new problems. 1. Write a Lewis structure for CH 3 OH and give the molecular geometry and predict the central bond angle about the C atom in CH 3 OH. See lecture text page 290 Table 10.2 of 8 th edition for Lewis structure of methanol. Tetrahedral 109.5 degrees See lecture text page 275 Table 10.2 of 7 th edition for Lewis structure of methanol. Tetrahedral 109.5 degrees 2. Write condensed structures for two compounds that are isomers and are primary amines and have the formulas C 6 H 15 N. Many answers are possible: CH 3 CH 2 CH 2 CH 2 CH 2 CH 2 NH 2 (CH 3 ) 2 CHCH 2 CH 2 CH 2 NH 2 3. Draw an expanded structural formula of a primary alcohol that is also a cyclic compound and has the formula C 6 H 12 O. Please refer to Midterm Exam I review notes from lecture.
