Organic Molecules in Chem

Organic Compounds: Compounds Containing C=O Groups

*Learning objectives:

1. To give an introduction to the chemistry of compounds containing the CO (carbonyl) group.
2. To begin to understand the chemistry of carbonyl compounds present in simple molecules and also in sugars, fats and proteins.

Diagnostic Test:

Try this short test. If you score more than 80 % you can use the chapter as a revision of your knowledge. If you score less than 80 % you probably need to work through the text and test yourself again at the end using the same test.
