In order to process and comprehend chemistry concepts, hands-on, active learning is a dynamic way to gain a deeper understanding. The following interactive simulations and thought activities will strengthen your recall and comprehension.
Molecule Polarity: Directions
The following simulation has three possible screens to assess molecule polarity:
1) Two Atoms Screen: In the simulation, you will be able to adjust the electronegativity of individual atoms, view the resulting electrostatic potential or electron density, and predict the bond polarity.
2) Three Atoms Screen: Explore the relationship between the bond dipoles and the molecular dipole, and observe the
molecule in an electric field.
3) Real Molecules:
Molecule Polarity Thought Activity:
• Predict how changing electronegativity will affect the bond polarity.
• Explain the relationship between the bond dipoles and the molecular dipole.
• Determine if a non-polar molecule can contain polar bonds.
• Describe how the ABC bond angle effects the molecular dipole.
• Compare the behavior of non-polar and polar molecules in an external electric field.
