Unformatted text preview: A C CHEM 1201 Sec 02 Spring 2006 EXAM 3 Chap 7 and 8 Dr Kolniak FORM1 If you have a question about the content of any of the problems or the answers provided, raise your hand. Make sure that every problem has an answer bubbled in on the scantron and DOUBLE check your answers on the scantron. Select the best answer (5 pts each). 1. Given the electronegativitv values for the following elements, arrange the following bonds in order of increasing bond polarity? Electronegativities: Q.2.5 O: 3.5 Cu: 1.8 Ge:2.0 QD <0 <> < Bonds: O G e, O C u, O O , C-C 0.r *-7 .o / a. C-C < C-Ge < C-Cu < C ^ * * b. C-Ge < C-Cu < C-O < C-C c. C-O < C-Ge < C-C < C-Cu d. C-Ge < C-C < C-Cu < C-O e. C-Cu < C-O < C-C < C-Ge 2. Which of the following has the larger ionization energy: Rb or I? Then select the correct statement that explains why your choice is correct. Rb, because the number of core electrons in the atom is less than that for I. p. Rb, because effective nuclear charge is greater than that of I. I, because the number of core electrons in the atom is greater than that for Rb d. I, because effective nuclear charge is greater than that of Rb ** e. I, because effective nuclear charge is less than that of Rb....
