Laboratory Follow-Up

Ionic bonding - understand the relationship between: (1) melting point and ion size (2) melting point and charge difference [see previous post for a link]

Solubility:
-if it dissolves in water, it is polar, thus possesses LD & DD (maybe even HB)
-if it does not dissolve, it is nonpolar, thus possesses only LD (no DD/HB of any significance)

Consider the following links for some alcohol solubility information
http://www.solubilityofthings.com/water/alcohols/
This next one discusses solubility much further down the "page", though the initial information fits in nicely with the next organic functional group...

Question: Why do white bears dissolve in water? Answer: Because they are polar.
