Chemistry Honors – Class 39

Seesaw Geometry

Dates

• Periods A, D – Tuesday, November 19th
• Period C – Wednesday, November 20th

New Material – VSEPR Geometry

• VSEPR Theory
  • What do these molecules look like?
  • Electron pairs repel – farthest apart as can be
  • All pairs determine the shape
  • only “name” bonding shape
• Application
  • See three charts in shared drive
  • determine the geometry of all pairs
  • then focus on bonding
  • examples from homework
• Practice
  • add to each molecule in the list
  • write the electron geometry and shape for each
  • draw sketch of 3D on each page

Homework

• Complete exercise for each compound
