Lab description and primary aims of the lab: 

When is a molecule polar? Change the electronegativity of atoms in a molecule to see how it affects polarity. See how the molecule behaves in an electric field. Change the bond angle to see how shape affects polarity.

Sample Learning Goals

·        Predict bond polarity using electronegativity values

·        Indicate polarity with a polar arrow or partial charges

·        Rank bonds in order of polarity

·        Predict molecular polarity using bond polarity and molecular shape

Technical requirements: 

For the part about real molecules Java is required
