2,4-Dichlorophenoxyacetic acid is an organic compound with the chemical formula Cl 2 C 6 H 3 OCH 2 CO 2 H.It is usually referred to by its ISO common name 2,4-D. [4] It is a systemic herbicide that kills most broadleaf weeds by causing uncontrolled growth, but most grasses such as cereals, lawn turf, and grassland are relatively unaffected.

The determination of chemical structure include (mainly): for the gaseous state: gas electron diffraction [2] and microwave spectroscopy [3]; for the liquid state: NMR spectroscopy [4] (note, obtaining precise structural information from liquids and solutions is still rather difficult compared to gases and crystalline solids)
The chemists on Wikipedia need to agree on appropriate settings for presenting chemical structures and reactions. The purpose of this workgroup is to discuss the various issues and come to a consensus on each one. Our decisions will then be uploaded to the structure drawing page and will also be briefly described in the style guide.
2,4-Dichlorophenol (2,4-DCP) is a chlorinated derivative of phenol with the molecular formula Cl 2 C 6 H 3 OH. It is a white solid that is mildly acidic (pK a = 7.9). It is produced on a large scale as a precursor to the herbicide 2,4-dichlorophenoxyacetic acid (2,4-D).

Theories of chemical structure were first developed by August Kekulé, Archibald Scott Couper, and Aleksandr Butlerov, among others, from about 1858. [4] These theories were first to state that chemical compounds are not a random cluster of atoms and functional groups, but rather had a definite order defined by the valency of the atoms composing the molecule, giving the molecules a three ...
The structural formula of a chemical compound is a graphic representation of the molecular structure (determined by structural chemistry methods), showing how the atoms are connected to one another. [1] The chemical bonding within the molecule is also shown, either explicitly or implicitly. Unlike other chemical formula types, [a] which have a ...
