Step 1 of 3

CHEM 1301 SPRING 2005 TEST 2 VERSION 1 NO CHEATING! BUBBLE IN “1” IN THE P COLUMN TO GET YOUR GRADE POSTED!!!!! [the only way you’ll find out how you did!] 1. An atom has 6 valence electrons – 2 are in an s-subshell and 4 in a p-subshell. Which group is the atom in (A) alkali metals (B) alkaline earth metals (C) pnictogens (D) chalcogens (E) halogens 2. How many protons, electrons and neutrons are there in the cation formed from an atom of magnesium that has a mass of 24 (A) 12 protons, 12 electrons, 12 neutrons (B) 12 protons, 10 electrons, 14 neutrons (C) 12 protons, 10 electrons, 12 neutrons (D) 14 protons, 12 electrons, 10 neutrons (E) 10 protons, 12 electrons, 12 neutrons 3. Which of the following ions is NOT likely to form from the appropriate atom (A) C 4+ (B) As 3- (C) Mg 2+ (D) Ti4+ (E) Na+ 4. When forming cations, electrons are removed first from orbitals that 3+e bigger rather than necessarily those with higher energy. Given this, what is the electron configuration of the cobaltic cation, Co (A) [Ar]4s 3d 7 (B) [Ar]4s 3d 4 (C) [Ar]3d 5 (D) [Ar]4s 3d10 (E) [Ar]3d6 5. Which of the following atoms, isotopes or ions contains 23 protons, 18 electrons and 27 neutrons (A) 45Co 5+ (B) 50Kr (C) 50V 5+ (D) 4Kr 5- (E) 5V 5- 6. Which of the following formulas represents aluminum sulfide (A) AlS (B) AlSO 3 (C) Al 3 2 (D) Al2(SO 3 3 (E) Al2 3 1 7. Chemists use Lewis dot structures primarily to help visualize: (A) protons in ionically bonded compounds (B) protons in covalently bonded compounds (C) electrons in ionically bonded compounds (D) electrons in covalently bonded compounds (E) pretty pictures 2- 8. How many dots should be included in the Lewis structure of SeCl4 (A) 32 (B) 34 (C) 36 (D) 102 (E) 104 9. The Lewis structure of which of the following molecules is best drawn using at least one double or triple bond (A) Si2Cl 6 (B) C 3 8 (C) P2 4 (D) Cl 2 2 (E) C 2r 4 10. When the best Lewis structure is drawnfor each of the following, which of the following species has the fewest lone pairs (A) carbonate (B) nitrate (C) sulfate (D) sulfite (E) nitrite 11. Within the context of this course, which of the following statements is false (A) Hydrogen will never make more than one bond (B) Carbon will never make more than four bonds (C) Compounds are known that contain noble gas atoms (D) Nitrogen will never make more than 3 bonds (E) Sulfur can form more than 4 bonds 12. Which of the following species does NOT violate the octet rule (A) XeF 2 (B) N 2 4 (C) SeCl4 (D) NO (E) BH 3 13. Which of the following compounds cannot exist (A) XeF 4 (B) PF 5 (C) SF6 (D) OF 4 (E) SF 4 2 14. The naming of polyatomic anions, while seemingly random, actually does have some rules. Two in particular concern the use of the prefix “bi” , which is used to indicate an extra positive hydrogen, and the difference between the suffices "ite" and "ate," which is based on number of oxygen atoms ("ite" means one less than "ate"). These are exemplified by the differences between carbonate and bicarbonate and sulfite and sulfate, respectively! Given this, what is the formula of biphosphite - 2- 2- 2- 3- (A) HP (B) (PO 4 2 (C) HPO 3 (D) HPO 4 (E) PO 3 15. Which of the following compounds is incorrectly named (A) Mg(OH) is2magnesium dihydroxide (B) CaO is calcium oxide (C) NH N4 is 3mmonium nitrate (D) K3PO i4 potassium phosphate (E) MgSO is magnesium sulfite 3 16. Which of the following formulas represents aluminum sulfite (A) AlS (B) AlSO (C) Al (SO ) (D) Al S (E) Al (SO ) 3 3 3 2 2 3 2 3 3 17. Which of the following substances is incorrectly matched with its shape (A) O 3 is bent (B) sulfur trioxide is trigonal planar (C) sulfur tetrafluoride is tetrahedral (D) sulfite is trigonal pyramidal (E) carbon tetrachloride is tetrahedral 18. Which of the following molecules would be expected to have the smallest angle at the central atom (A) carbon dioxide (B) sulfur dioxide (C) selenium trioxide (D) silicon tetrafluoride (E) water 19. Which of the following bonds should be the most polar (A) B-F (B) C-O (C) N-Cl (D) B-Br (E) C-F 20. Which partial charge labels in the following bonds is/are correct I. δO-S δ+ II.δ+S-Cl δ− III.δ+Cl-O δ- (A) I only (B) II only (C) III only (D) all of them are correctly labeled (E) I and II only 3
