Advanced Inorganic Chemistry Chemistry 4610 Fall 2007 Ramon Lopez de la Vega 1. Draw the most stable Lewis Dot Structures and molecular shapes for each of the following molecules or molecular ions. If there are energetically equivalent resonance structures show them. ( 20) SO 3 SO 3 -2 NCO -1 ONC -1 2. Determine the Schoenflies Point Group for the molecules drawn below (20): Br Co Br Cl Br Cl Cl Cl Co Cl Cl Cl Cl Br Br Co Cl Br Cl Br Br Cl Co Cl Cl Cl Br Br These may be in a different order than was in the blackboard. 3. What is the difference between formal charge and oxidation state? 4. Why is the Ionization energy of Cl less than the Ionization Energy of F? ( 5 points) Why is the Ionization energy of N greater than the Ionization Energy of O? ( 7 points) Why do the atomic radii increase in the order Sc Y La while in the adjacent group it increases in the order Ti Zr ~Hf ( 8 points ) 5. Using Slater’s rules determine what is the effective nuclear charge for the last electron added to

Unformatted text preview: the metal Pb. 6. For the following four molecules, assign Lewis Dot Structure, Electronic Geometry, Molecular Structure and most likely hybridization. If there are resonance structures, show them. PF 5 SO 4-2 IF 3 NO 3-1 7. In class we discussed that the octet rule really only had to be followed by four atoms in molecule formation. Identify the four atoms and explain why the other atoms may be exceptions to the rule. 8. For the following electron configurations, identify which would be that of the ground state of an ion and which would be that of an atom. Identify a possible element (specify charge) and also identify which one(s) cannot possibly a ground state configuration. a. ns 2 (n-1)d 8 b. ns (n-1)d 8 c. ns 1 (n-1)d 8 d. ns 1 (n-1)d 4 e. ns 1 (n-1)d 5 f. ns 2 (n-1)d 8 np 2 g. ns 2 (n-1)d 10 np 2 h. ns (n-1)d 10 np 2 I. ns (n-1)d 10 np j ns 2 (n-1)d 10 np 4...
