aldehydes

Terminal carbonyl compounds

Aldehydes is the plural of aldehyde, a class of organic compounds containing a carbon atom double-bonded to oxygen and single-bonded to hydrogen.

Aldehydes occur throughout chemistry and biology—formaldehyde is a preservative, acetaldehyde forms when alcohol metabolizes, and benzaldehyde gives almonds their scent.
