What is aldol?

  • (noun): An oily colorless liquid obtained by the condensation of two molecules of acetaldehyde; contains an alcohol group (-OH) and an aldehyde group (-CHO).
    Synonyms: aldehyde-alcohol


An aldol or aldol adduct (from "Aldehyde alcohol") is a beta-hydroxy ketone or aldehyde, and is the product of aldol addition (as opposed to aldol condensation, which produces an α,β-unsaturated carbonyl moiety).
