Monochlorophenol

Last updated

The monochlorophenols are chemical compounds consisting of phenol substituted with a chlorine atom. There are three isomers, 2-chlorophenol, 3-chlorophenol, and 4-chlorophenol.

Chemical compound Substance composed of multiple elements

A chemical compound is a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds. A chemical element bonded to an identical chemical element is not a chemical compound since only one element, not two different elements, is involved.

Phenol chemical compound

Phenol is an aromatic organic compound with the molecular formula C6H5OH. It is a white crystalline solid that is volatile. The molecule consists of a phenyl group (−C6H5) bonded to a hydroxy group (−OH). It is mildly acidic and requires careful handling due to its propensity for causing chemical burns.

In chemistry, isomers are ions or molecules with identical formulas but distinct structures. Isomers do not necessarily share similar properties. Two main forms of isomerism are structural isomerism and stereoisomerism.
