Definitions

1. These are organic chemicals that feature a carbonyl group attached to at least one hydrogen atom, often utilized in industry and organic synthesis for their importance in flavors, fragrances, and polymers
2. They represent a class of organic compounds with a carbonyl group bonded to hydrogen, commonly found in various industrial applications including flavoring and fragrance production, as well as in the manufacturing of resins and polymers
3. These compounds are characterized by a carbonyl group linked to at least one hydrogen atom, playing key roles in the production of scents, flavors, and as intermediates in chemical synthesis

Etymology: The word's most surprising link runs through alcohol. In the 1830s, the German chemist Justus von Liebig was working on compounds derived from alcohol by removing hydrogen, and he coined a name for one of them by contracting the Latin phrase "al(cohol) dehyd(rogenatum)", meaning "alcohol deprived of hydrogen." The result, "Aldehyd" in German, was the source of the English form. The English word therefore carries a compressed chemical recipe inside it. Its first half, "al", is a clipping of "alcohol", a word that itself traces back through Arabic "kuhl", a fine powder used as eye cosmetic, to the Akkadian "guhlum". The second half, "dehyd", comes from "dehydrogenatum", a Latin-based term describing the removal of hydrogen. The plural simply adds the usual "-s" to the singular "aldehyde", one of many chemical names that form plurals in the regular way.
