Intermolecular Forces Determine State of Matter Flashcards
What are Dipole-Dipole Interactions?
Dipole-Dipole Interactions occur between molecules that have a permanent dipole moment.
What are the Intermolecular Forces?
The Dipole-Dipole Forces, the dispersion forces (London forces), and the hydrogen bonds.
What are the Dispersion Forces?
Electron distribution is unsymmetrical at any instant instantaneous dipoles develop. Strength depends on molecular weight, as molecular weight increases the number of electrons increases.
What is an Electric Dipole?
An electric dipole is a separation of positive and negative charges.
What is an Electret?
A permanent electric dipole is called an electret.
What is a Hydrogen Bond?
Hydrogen covalently bonded to N, O, or F in one molecule and a non-bonded pair of electrons on N, O, or F in another molecule attract or interact.
