The 5 basic shapes for ABn molecules
Additional molecules can be made by removing corner atoms from the 5 basic shapes. This one starts with a tetrahedral.
In general, each non-bonding pair, single bond or multiple bond produces an electron domain around the central atom.
Balloons tied together at their ends naturally adopt their lowest-energy arrangement.
The bond angles decrease as the number of nonbonding electron pairs increase.
Electron domains for multiple bonds exert greater repulsive forces on adjacent electron domains than single bonds.
