CH32 – Shapes and Names

over

Dates

  • P4 – Thursday, November 9th
  • P5 – Friday, November 10th
  • P7 – Friday, November 10th

Recap – VSEPR Shapes

  • guiding principles
  • where are reference materials (charts)? CH29
  • how do we use the charts?

Example: ClF2+1

  • Lewis Structure
  • Total valence electrons
  • Formal Charge (each atom)
  • Domains / Lone Pairs
  • electron geometry
  • shape of structure
  • angle(s) within structure

Work Time

  • remainder of the class period
  • fill in missing information
  • correct / update previous information

List for Each Substance Required (so far!)

  • formula
  • total valence electrons
  • Lewis structure
  • formal charge on each atom
  • bonding pairs / lone pairs
  • bonding domains / lone pairs
  • electron geometry
  • structure shape
  • bond angle(s)

Homework

  • finish all of the work needed on paper (see list)
  • some will have model to build (that’s OK)

Quiz – Next Class Meeting

  • Formula –> Name
  • Total Valence Electrons
  • Lewis Structures
  • Formal Charge
  • Bonding Pairs / Lone Pairs
  • Bonding Domains / Lone Pairs
  • Provided: Periodic Table
