Molecular Polarity - Questions

The Molecular Polarity Concept Builder is comprised of 54 questions organized into 18 Question Groups and spread across three different difficulty levels.  The Apprentice Difficulty Level includes 6 Question Groups and 18 total questions. Each question presents information about three molecules and students must decide if each molecule is polar or non-polar. The presented information includes the AXE notation, the molecular geometry, and a ball-and-stick model. The Master Difficulty Level includes 6 Question Groups and 18 total questions. Each question provides a chemical formula and Lewis electron dot structure for a molecule. Students must determine the molecular geometry from the electron dot structure and then determine if the molecule is polar or non-polar. All structures are limited to a maximum of four electron groups around the central atom. The Wizard Difficulty Level is similar to the Master Level with the exception that all structures have five or six electron groups around the central atom. Students must still determine the molecular geometry and the polarity of the molecule.
