Chemistry 13 Name _______________________ Exam III Form A Section _______________________ April 10, 2007 Student No. _______________________ IMPORTANT : On the scantron (answer sheet), you MUST clearly fill your name , your student number , section number , and test form (white cover = test form A; yellow cover = test form B). Use a #2 pencil. There are 25 questions on this exam. Check that you have done all of the problems and filled in the first 25 bubbles on the scantron. The maximum score on this exam is 25 points. Your score will be reported in percent (max 100%). Exam policy Calculators with text-programmable memory are not allowed. Relevant data and formulas, including the periodic table, are attached at the end of this exam. Your grade will be based only on what is on the scantron form. The answer key will be posted on the web after the exam (on the Exam Schedule page). Hints As you read the question, underline or circle key words to highlight them for yourself. Avoid errors from "mis-reading" the question. Pay attention to units and magnitudes (decimal places) of numbers obtained from calculations. There is no penalty for guessing.

CHEMISTRY 13 EXAM Apr. 10, 2007 FORM A ------------------------------------------------------------------------------------------------------------ 1. Which of the following transition metal complexes will be attracted to a magnet? A. [Mn(H 2 O) 6 ] 2+ (weak ligand field) B. [Zn(H 2 O) 6 ] 2+ (weak ligand field) C. [TiCl 4 ] (weak ligand field) D. [Ru(NH 3 ) 6 ] 2+ (strong ligand field) E. [Zn(NH 3 ) 4 ] 2+ (strong ligand field) ------------------------------------------------------------------------------------------------------------ 2. Which of the following is a true statement: I. Metals always gain electrons when forming compounds. II. Nonmetals form anions or oxyanions in water. III. Oxides of metalloids are soluble in both acidic and basic solutions. IV. Nonmetals are excellent electrical conductors. A. I only B. III only C. I, III, and IV only D. II and III only E. I, II, III and IV ------------------------------------------------------------------------------------------------------------ 3. According to crystal field theory, which of the following statements about the energies of d orbitals in an octahedral transition metal complex are true? I. The dz 2 orbital increases in energy due to electronic repulsion from ligand electrons. II. The dxy orbital is lower in energy than dz 2 because it points between the ligands and therefore experiences less electronic repulsion. III. Low spin electronic configurations are observed when the d-d energy separation, Δ , is less than the spin pairing energy, P. A. only I is true
