🤓 Based on our data, we think this question is relevant for Professor Patell's class at K- STATE.

1. Draw the Lewis structure of the azide anion N _{3}^{-}. Give its geometry. Is N_{3}^{-} polar (in the sense of having a non-zero electric dipole moment)?

2. Draw the Lewis structure of nitryl fluoride NO _{2}F (N is at the center). Give its geometry, including a discussion of the angles. Is NO_{2}F polar?

3. Rationalize the following bond angles: NH _{3} 106.6°; NF_{3} 102.2°; NCl_{3} 106.8°.
