Intermolecular Forces Determine State of Matter

Question 1

What are Dipole-Dipole Interactions?

Answer 1

Dipole-Dipole Interactions occur between molecules that have a permanent dipole moment.

Question 2

What are the Intermolecular Forces?

Answer 2

The Dipole-Dipole Forces, the dispersion forces (London forces), and the hydrogen bonds.

Question 3

What are the Dispersion Forces?

Answer 3

Electron distribution is unsymmetrical at any instant instantaneous dipoles develop. Strength depends on molecular weight, as molecular weight increases the number of electrons increases.

Question 4

What is an Electric Dipole?

Answer 4

An electric dipole is a separation of positive and negative charges.

Question 5

What is an Electret?

Answer 5

A permanent electric dipole is called an electret.

Question 6

What is a Hydrogen Bond?

Answer 6

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.
