How to pronounce“aldehydes”in English

Aldehydes, instead of ‘-ol’ you add ‘-al’, so from ethane you get ethanal.

Aldehydes are just dehydrogenated alcohols, ketones are just aldehydes bonded to R-groups on both sides

Both aldehydes and ketones will react with a diatomic halogen like bromine at the alpha position in the presence of a base.

Other aldehydes go by their IUPAC names.

So aldehydes and ketones are really useful for organic chemists, and there's a lot of information to keep straight!

Like aldehydes, ketones take priority over alcohols, and therefore priority over double bonds, triple bonds, and any of the substituents we’ve seen so far.

Remember that aldehydes and ketones react easily with amines to form imines.
