Ester - Wikipedia
In chemistry, an ester is a functional group derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (R ′). Analogues derived from oxygen replaced by other chalcogens belong to the ester category as well. [1] .
