NSM 12C PAL Worksheet Lewis Structures & Trends Name:________________ In your groups, read through and come to a consensus choice for what you feel is the correct answer for the following questions. 1. Which of the following would be properly classified as a set of covalent molecules? A) CO2, NH4Cl, C2H6 B) CO2, HCN, O2 C) NaClO4, C4H10, NH3 D) NaCl, CH4, S8 E) AgCl, ScF3, P4 2. Which of the following represent the Lewis structure for N? A) B) C) D) E) 3) Draw the Lewis structure for S2⁻? 4) Identify the compound with the highest magnitude of lattice energy. Explain the reasoning behind your choice below: A) LiCl B) NaCl C) CsCl D) KCl 5) Place the following elements in order of increasing electronegativity. K Cs P A) P < Cs < K E) Cs < P < K B) P < K < Cs C) K < P < Cs D) Cs < K < P 6) Choose the bond below that is most polar. Explain the reasoning behind your choice below: A) C-‐C B) C-‐F C) F-‐F D) C-‐N E) C-‐O 7) Place the following in order of decreasing bond length. H-‐F H-‐I H-‐Br A) H-‐I > H-‐Br > H-‐F B) H-‐Br > H-‐F > H-‐I D) H-‐F > H-‐I > H-‐Br E) H-‐F > H-‐Br > H-‐I Explain the reasoning behind your choice below: C) H-‐I > H-‐F > H-‐Br 8) Identify the shortest bond.
