Exceptions to this structure are formic acid(HCOOH) and oxalic acid(HOOCCOOH). The number of carbon atoms ranges from 1(formic) to 26(cerotic), the carbon of the terminal group being counted as part of the chain. Carboxylic acids include the large and important class of fatty acids..., and may be either saturated or unsaturated. A few contain halogen atoms(chloroacetic). There are also some natural aromatic carboxylic acids(benzoic, salicylic) as well as alicyclic types(abietic, chaulmoogric).  2, record 2, English, - carboxylic%20acid

With the halogens, fluorine, chlorine, bromine, and iodine, hydrogen forms hydrides containing 1 atom of hydrogen per atom of halogen. These compounds are usually referred to as hydrogen halides, for example, hydrogen chloride, HCl, or as hydrohalic acids, for example hydrochloric acid. The hydrogen halides are gases at room temperature.  2, record 3, English, - hydrogen%20halide
