Web1. Acting as a nucleophile, the alkoxide ion is attracted to the carbon atom of the carboxyl group. 2. The oxonium loses a proton. 3. An unshared electron pair from the alkoxide ion moves toward the carbonyl carbon, assisting the hydroxyl group's exit. Methyl ester formation. Methyl esters are often prepared by the reaction of carboxylic acids ... WebA carboxylate ion (see figure below), in which the negative charge is spread over two different oxygen atoms through resonance structures, is more stable than an isolated oxygen-centered anion. Carboxylic acids are used in a variety of environments. Formic acid acts as a protective chemical for many stinging insects and plants.

Thus, in a monohaloacetic acid, a single halogen would replace a hydrogen atom. For example, chloroacetic acid would have the structural formula CH2ClCO2H. In the same manner, in dichloroacetic acid two chlorine atoms would take the place of two hydrogen atoms (CHCl2CO2H).
