{16} Intermolecular Forces

Question 1

Dispersion Force?

Answer 1

Due to instantaneous dipole moments causing fluctations in the electron cloud
All molecules and atoms have this
Least Powerful Bond

Question 2

Dipole-dipole force?

Answer 2

Only in polar molecules
* 3rd Most Powerful Bond*

Question 3

Hydrogen bonding?

Answer 3

Molecules containing H bonded to F, O, or N
2nd Strongest Bond

Question 4

Ion-Dipole Force?

Answer 4

Mixtures of ionic compounds and polar compounds
Strongest Bonds

Question 5

Define:

Soluble?

Answer 5

Soluble: A molecule (s) fully dissolves in another liquid molecule (l). Thus, they have similar IMFs.
Insoluble: A molecule (s) does not fully dissolve in another liquid molecule(l). Thus, they do not have similar IMFs.

Question 6

Define:

Miscibility?

Answer 6

Miscible: A polar molecule (l) fully mixes in another polar liquid molecule (l). Thus, they have similar IMFs. (**If **
Immiscible: A non-polar molecule (l) does not fully mix in another polar or non-polar liquid molecule (l). Thus, they do not have similar IMFs.
