What you'll read
The real module and unit structure of CHM424, taken from the course material NOUN publishes.
One paragraph, so you can see how it reads
CHM424 · UNIT 1: Properties of solvents
Based on polarity, solvents can be classified as polar and non-polar. As a rule, polar solvent (such as water) are those that dissolve polar compounds while nonpolar compounds are dissolved by non-polar solvents.
What you should be able to do
- Explain the physical properties of non-aqueous solvents and their significance.
- Classify non-aqueous solvents based on various principles.
- Describe the different types of solute-solvent interactions.
- Discuss the chemistry of selected non-aqueous solvents.
- Compare and contrast the behavior of non-aqueous solvents with aqueous media.
