Bond Angles Video Lessons

Concept: VSEPR Model for Bonding

# Problem: 1. Draw the Lewis structure of the azide anion N  3-. Give its geometry. Is N3- polar (in the sense of having a non-zero electric dipole moment)?  2. Draw the Lewis structure of nitryl fluoride NO 2F (N is at the center). Give its geometry, including a discussion of the angles. Is NO2F polar?   3. Rationalize the following bond angles: NH 3 106.6°; NF3 102.2°; NCl3 106.8°.
