9.0 Props – Molecular Structure

Subjects: Molecular structure, orbitals, VSEPR theory

Description: Models are used to illustrate the geometry of molecular orbitals and VSEPR theory.

Materials:

  • Space-filling foam tetrahedral and linear models
  • Foam molecular model & hybrid orbital kit (located in drawers next to hood)
  • Wood molecular model kit (in drawers next to hood)
  • Pipe cleaners (for adding double and triple bonds to wood models)

Procedure:

  1. Create and display models of different molecules including:

    Acetylsalicylic acid, ethane, acetylene, acetic acid, phosgene, Phosphorous Trifluoride Dichloride (PF3Cl2), cysteine, carbon dioxide (CO2), Water (H2O), Boron trifluoride (BF3)and Nitrogen Trifluoride (NF3 )

  2. Use the pipe cleaners to demonstrate double bonds, triple bonds, and lone electron pairs

Discussion:

None.

Safety:

None.

Disposal:

None.
