Molecular Polarity

The Molecular Polarity Concept Builder includes 54 questions that focus student attention on the polarity of molecules. The 54 questions are organized into 18 Question Groups and spread across three difficulty levels. The Apprentice Difficulty Level presents learners with the AXE notation, the molecular geometry, and the ball-and-stick model of three different molecules; learners must decide which are polar. The Master Difficulty Level presents learners with the chemical formula and the Lewis electron dot structure of a molecule; learners must identify the molecular geometry and decide if the molecule is polar or non-polar. All structures have a maximum of 4 electron groups around the central atom. The Wizard Difficulty Level is similar to the Master Level except for the fact that all molecules have 5 or 6 electron groups around the central atom.

Question-specific help is provided for each of the 18 Question Groups. The built-in feedback makes this Concept Builder a perfect candidate for a classroom activity. When used with our Task Tracker program, the Concept Builder can be assigned as either in-class or out-of-class work.
