###### FREE Expert Solution

We’re being asked to approximate the **bond angles of the two carbon atoms in glycine**. Since we have the Lewis structure for glycine, we 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˚

* *Electron groups* include lone pairs and atoms around the central atom
