CH32 – Shapes and Names

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)
