Chemistry:Dibromophenol

From HandWiki

Dibromophenols form a group of aromatic chemical compounds which are both phenols and bromobenzenes. The structure consists of a benzene ring with an attached hydroxy group (-OH) and two bromine atoms (-Br) as substituents. There are six structural isomers, each with the molecular formula C6H4Br2O, which differ by arrangemnt of the substituents.
