Haloacetic acids are carboxylic acids in which a halogen atom takes the place of a hydrogen atom in acetic acid. Carboxylic acids are Organic acids characterized by the presence of a Carboxyl group, which has the formula -C(=OOH usually written -COOH or -CO2H Abundance Owing to their high Reactivity, the halogens are found in the environment only in compounds or as Ions Halide ions and oxoanions Hydrogen (ˈhaɪdrədʒən is the Chemical element with Atomic number 1 Acetic acid, also known as ethanoic acid, is an organic chemical compound, giving Vinegar its sour taste Thus, in a monohaloacetic acid, a single halogen would replace a hydrogen atom. For example, chloroacetic acid would have the structural formula CH2ClCO2H. Chloroacetic acid is the Chemical compound with the formula ClCH2CO2H In the same manner, in dichloroacetic acid two chlorine atoms would take the place of two hydrogen atoms (CHCl2CO2H). Dichloroacetic acid, often abbreviated DCA, is a Chemical compound, an Acid, and an analogue of Acetic acid in which two of the Chlorine (ˈklɔriːn from the Greek word 'χλωρóς' ( khlôros, meaning 'pale green' is the Chemical element with Atomic number 17 and
