Part E: Polarity of Molecules
After watching the video on Polarity of Molecules, determine if the entire molecule for each structure
shown below is polar or nonpolar. In addition, be sure to indicate polar bonds using arrows or partial
charge (delta ō signs) as shown in the first example. Remember, a C-H bond is nonpolar and nonpolar
bonds would not require an arrow in this process.

The Lewis models (at least) should be completed before coming to lab. Be sure to consider the Lewis dot model and the ball-and-stick model as two separate items. The Lewis model should not attempt to indicate geometry. The ball-and-stick model does not need to show multiple bonds or the positions of lone pairs of electrons but should depict molecular geometry. Since ions have a net charge, the issue of polarity is usually unimportant for them. You can skip the polarity analysis for the ions. Fill in the all blanks!arrow_forward
