Textbook and Chapter: Carey and Giuliano 8th Ed. (2010), Chapter 1

Keywords: formal charge, Lewis structures, resonance

Description: This mendel set goes through the basics of structure:

  • Converting between formulas and carbon skeleton diagrams ("Zig-zag" structures)
  • Determining formal charge
  • Identifying implicit hydrogens and lone pairs
  • Resonance and arrow pushing

Total Problems: 7

Problem # 755

The nitrosyl cation is shown below. Also shown are several proposed resonance arrows, only one of which is correct.

Draw the resonance forms that would follow from each set of arrows, and include formal charges. Which one is the correct resonance form? Explain your reasoning.

Problem # 309

Convert each formula to a carbon skeleton diagram, or vice-versa.
