(27 cards)
The forces that hold atoms to form a molecule
Intramolecular forces
Types of Intramolecular Forces
- Ionic
- Metallic
- Covalent
Transfer of electron (metal + nonmetal)
Ionic
Share of electron (metal + metal)
Metallic
Share of electron (nonmetal + nonmetal)
Covalent
Formal Charge
Ionic
Partial Charge
Metallic, Covalent
Forces between molecules
Intermolecular Forces
Types of Intermolecular Forces
- Ion-Ion
- Ion-Dipole
- Hydrogen Bonding
- Dipole-Dipole
- Ion-induced Dipole
- Dipole-induced Dipole
- London Dispersion Force
Ionic + Ionic
Ion-Ion
Ion + Polar covalent
Ion-Dipole
2 Polar covalent with high E. (O,N, F)
Hydrogen Bonding
Polar covalent + Polar Covalent
Dipole-Dipole
Ion + Non-polar covalent
Ion-induced Dipole
Polar covalent + Non-polar covalent
Dipole-induced Dipole
Non-polar covalent + Non-polar covalent
London Dispersion Force
Relative Strengths of Intermolecular Forces
- Ion-Dipole (Strongest)
- Hydrogen Bonding
- Dipole-Dipole
- Dipole-induced Dipole
- London Dispersion Forces (Weakest)
Density: Very High
Solid
Density: High
Liquid
Held by very strong forces of attraction
Particles are not free to move
Particles vibrate about in a fixed position
Solid
Held together by strong forces of attraction
Particles are able to slide past one another
Liquid
Diffusibility: Extremely slowly
Solid
Diffusibility: Slow
Liquid
Compressibility: Slightly compressible
