| Describe the Valence Shell Electron Pair Repulsion (VSEPR) theory |
answer
| Electron groups (lone pairs, single bonds, multiple bonds, and even single electrons) repel each one another through coulombic forces |

question
| what happens to the geometry of a molecule with trigonal planar geometry if it has a double bond? |
answer
| the bond angles are closer to 121.9 and 116.2 degrees degrees instead of 120 degrees because the double bond contains more electron density than a single bond and therefore exerts a slightly greater repulsion on the single bonds |
