Make careful observations about the following two molecules. List at least 5 about each one. Then click on the molecules and move them around .  Make 5 additional observations about each molecule.  If you don't see the molecule, make sure Chime is loaded.

Now observe the molecules using the following video clip.

 Develop a well written constructed response item that includes the following that compares and contrasts the two molecules. Be sure to include the following information in your response.  You may link to the Chime guide and or the ChemSketch guide to assist you as you write your response.

   1. Name the two molecules.

   2.  Calculate or describe for each molecule:

• Bond length (CC; CH)

• Bond angle (CC; CH)

• Polarity of bond (CC; CH)

• Polarity of molecule

• Shape

• Type of bond

• Resonance

• Molecular formula

• Empirical formula

• Bond energy

• Solubility

• Reactivity

• Boiling point

3.  The role of intermolecular forces.
