Tetrahedral
4 bonded pairs, 0 lone pairs or 4 electron pairs. 109.5 degrees
1 of 10
Octahedral
6 electron pairs. 90 degrees
2 of 10
Trigonal planar
3 electron pairs. 120 degrees
3 of 10
Pyramidal
3 bonded pairs, 1 lone pair. 107 degrees
4 of 10
Linear
2 electron pairs. 180 degrees

Electronegativity
A measure of the attraction of a bonded atom for the pair of electrons in a covalent bond
7 of 10
London forces (induced dipole-dipole interactions)
Weak intermolecular forces that exist between all molecules. Relative strength increases as the number of electrons increase
8 of 10
Permanent dipole-dipole interactions
An attractive force between permanent dipoles in neighbouring polar molecules
9 of 10
Hydrogen bond
A strong dipole-dipole attraction between an electron-deficient hydrogen atom on one molecule and a lone pair of electrons on a highly electronegative atom on a different molecule
