Shapes of Molecules
Rules
3 1 107 Trigonal pyramidal
2 2 104.5 Bent line
2 0 180 Linear
3 0 120 Trigonal Planar
5 0 90/120 Trigonal Bipyramidal
6 0 90 Octahedral
If there is a set of paired electrons it pushes the bonding electron pairs further
Rules
- Electron pairs move as far apart as possible, in order to minimise their mutual repulsion
- Lone electron pairs repel more strongly than bonding electron pairs
