Polarity Flashcards
Intramolecular Forces:
A force acting between atoms within a molecule. These forces are relatively strong.
Examples: covalent bonding, ionic bonding
Intermolecular Forces:
Intermolecular Forces: Attractive forces (electrostatic in nature) acting between molecules, atoms, ions. These forces are relatively weak.
Hydrogen bonding
Dipole Dipole
London Dispersion Forces/Van der Waals forces
Types of Intermolecular Forces (6)
Hydrogen Bonding Dipole - Dipole Induced Dipole - Induced Dipole Ion - Induced Dipole: Ion - Ion Ion - Dipole
Hydrogen Bonding
Hydrogen bonded to N, O, or F is attracted to lone pairs of electrons on other N, O or F
Dipole - Dipole
Interaction between two polar molecules
Opposite dipoles attract (δ– and δ+)
Induced Dipole - Induced Dipole
London dispersion forces
- Molecules interact randomly and distort each other’s electron clouds, causing temporary dipoles
Strongest to weakest Bonds:
