Question 1

London dispersion

Answer 1

the weakest intermolecular force.

Question 2

Dipole-dipole

Answer 2

attractive forces between the positive end of one polar molecule and the negative end of another polar molecule.

Question 3

Hydrogen bonds

Answer 3

a special type of dipole-dipole attraction between molecules, not a covalent bond to a hydrogen atom.

Question 4

Ranking intermolecular attractions from weakest to strongest and vice versa in solution

Answer 4

ionic, covalent, hydrogen bonding, dipole dipole, and london dispersion

Question 5

Determine whether a molecule is polar or nonpolar based on its structure

Answer 5

a nonpolar molecule will always be symmetrical and its dipole movements will cancel out (neutral charge).

Question 6

Determine what type of intermolecular attractions a particular molecule will be able to form based on its structure

Answer 6

Based on the

Question 7

Determine whether a molecule will be soluble in water based on its structure

Answer 7

Molecules with fewer than 4-5 C atoms per hydrogen bonding group will likely be soluble in water.
