Acetals

Part of speech: noun

Definitions

1. A category of organic substances created through the combination of aldehydes and alcohols, exhibiting a central carbon atom bonded to an alkoxy group and another organic moiety
2. These compounds emerge from aldehyde and alcohol interactions, identified by a carbon atom that is connected to an -OR group alongside another carbon chain or ring structure
3. Chemical substances produced when an aldehyde reacts with two alcohol molecules, resulting in a compound featuring a carbon atom bonded to two alkoxy groups

Etymology: Acetals are a plural form, and the word they come from is a compound built from two chemistry terms. "Acetal" joins "acet(ic)", from acetic acid (the acid in vinegar, whose name comes from Latin "acetum", meaning sour wine), with "al(cohol)". The ending reflects the chemical family: acetals are formed when an aldehyde or ketone reacts with alcohols, so the name records both the acetic link and the alcohol component.
