###### FREE Expert Solution

We’re being asked to identify the **bond angle **in **IF**_{4}** ^{-}**. Since we don’t know the Lewis structure for IF

_{4}

^{-}, we need to do the following steps:

*Step 1:* Determine the central atom in this molecule.

*Step 2:* Calculate the total number of valence electrons present.

*Step 3:* Draw the Lewis structure for the molecule.

*Step 4:* Determine the number of electron groups around the indicated atom.

*Step 5: *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˚
