SG 2.4

Question 1

What are the different types of inter molecular attraction by weakest to strongest.

Answer 1

London Dispersion, Dipole-Dipole, Hydrogen Bond

Question 2

How can you tell if a molecule is polar or nonpolar?

Answer 2

If the arrangement is symmetrical and the arrows are of equal length, the molecule is nonpolar.

Question 3

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

Answer 3

The best way to determine what kind of intermolecular bonding the molecules will undergo is by looking at the Lewis structure. Just because there is H and N,O,F on the molecule does not mean they can undergo hydrogen bonding, since the requirement is the H is bonded specifically to N, O, or F.

Question 4

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

Answer 4

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