Chemistry Honors – Class 43

Resonance

Dates

  • Period B: Thursday, April 16th
  • Periods D, G: Friday, April 17th

Lewis Dot Structures – Activity

  • Complete on paper
  • One formula per side of sheet of paper
  • name compound
  • determine total valence electrons
  • draw Lewis structure
  • formal charge for each atom
  • bond polarity (of each bond – use arrows)
  • identify lone, total pairs around central atom

Compounds

  • SiCl4
  • NCl3
  • OF2
  • RnF2
  • BrF3
  • SF4
  • SbCl5
  • XeF4
  • IF5
  • SF6
  • H2CO
  • HCN
  • ClO3-1
  • CO3-2
  • NH4+1

Things to Consider

  • Octet Rule (CNOF only)
  • H, F bond only once
  • central atom probably closest to carbon
  • does formal charge match what you expect?
  • is there resonance? how do I show this?
