Ester: Characters & Applications

In chemistry, an ester is a compound derived from an acid (either 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′). These compounds contain a distinctive functional group. Analogues derived from oxygen replaced by other chalcogens belong to the ester…
