Chapter 7, Problem 113E

Use the simulation (http://openstaxcollege.org/l/16MolecPolarity) to perform the following exercises for a real molecule. You may need to rotate the molecules in three dimensions to see certain dipoles.

(a) Sketch the bond dipoles and molecular dipole (if any) for ${\text{O}}_3$ Explain your observations.

(b) Look at the bond dipoles for NH3. Use these dipoles to predict whether N or H is more electronegative.

(c) Predict whether there should be a molecular dipole for ${\text{NH}}_3$ and, if so, in which direction it will point. Check the molecular dipole box to test your hypothesis.
