Polar Molecules
|
High melting and boiling pt.
(but less than an ionic compound) Usually solid or liquid Attraction between changes cause the molecules to stick together |
|
|
Non-Polar Molecules
|
Low melting and boiling pt.
Usually gases No charges, no attractions so the substance is usually a gas. |
