Properties of Aldehydes and Ketones

Aldehydes and ketones contain the same functional group, for example, butanal and butanone both contain the same carbonyl functional group (C=O). So how would you tell if a substance was butanal or butanone?
AUS-e-TUTE has just added new resources to help you understand the similarities and differences in the chemical and physical properties of aldehydes and ketones (as represented by alkanals and alkanones). AUS-e-TUTE Members should log-in to use the new tutorial, game, test and exam with worked solutions.
If you are not an AUS-e-TUTE member there is currently a "free-to-view" tutorial on this topic at https://www.ausetute.com.au/ketones.html

Alkanols vs Alkanals

Question: Differentiate between alkanols and alkanals.

Answer: Alkanols and alkanals are both organic (carbon containing) compounds but they have different functional groups.
Alkanols contain the OH (hydroxyl) functional group.
Alkanals contain the C=O (carbonyl) functional group on a terminal (end) carbon atom of the carbon chain.
Because they have different functional groups they undergo different chemical reactions and will have different physical properties.
The physical and chemical properties of alkanols, for example, can be found at AUS-e-TUTE's page on Properties of Alkanols.

Aldehydes and Ketones

Help with naming aldehydes and ketones is now available.
AUS-e-TUTE has just uploaded new resources (games, tests, tutorials) to introduce students to the preferred IUPAC system for naming alkanals (simple aldehydes) and alkanones (simple ketones).

AUS-e-TUTE members should log-in to use these new resources: http://www.ausetute.com.au
