🤓 Based on our data, we think this question is relevant for Professor Dixon's class at UCF.
Consider the Lewis structure for glycine, the simplest amino acid:
What are the approximate bond angles at the nitrogen?
We’re being asked to identify the bond angles around nitrogen in glycine. Since the Lewis structure for glycine is already given, we simply need to do the following steps:
Step 1: Determine the number of electron groups around the indicated atom.
Step 2: Determine the electron geometry and bond angle using this:
Electron Regions Electronic Geometry Bond Angles
2 linear 180˚
3 trigonal planar 120˚
4 tetrahedral 109.5˚
5 trigonal bipyramidal 90˚, 120˚, and 180˚
6 octahedral 90˚ and 180˚
