What is the VSEPR Theory?
Electron rich groups REPEL each other through coulombic forces; electron groups arrange themselves as FAR apart from each other as possible
What are coulombic forces (electrostatic force)?
The force of attraction or repulsion between 2 electrically charged particles; same charge repel while opposites attract
Electron groups
LP pairs, single, double, or triple bonds around a central atom; when counting electron groups, all electron groups are counted equally (as 1 group)
What is the electron geometry?
The arrangement of THE ELECTRONS around the central atom
What is molecular geometry (shape)?
Depends on electron geometry and describes the arrangement of the atoms within a molecule
Components of a VSEPR sketch?
straight line: bond in plane of paper / hatched wedge: bond coming towards you / solid wedge: bond running away from you
