Arenes

Arenes are aromatic organic hydrocarbons, meaning they have a ring structure as their base. They have areas of delocalised electrons and the most simple and common of these is Benzene, which has the chemical formula C6H6 and a planar ring structure. It has three double and three single covalent bonds as represented in diagrams, but like all other arenes based on its structure, it has areas of delocalised electrons between the core 6 carbon atoms. The delocalised electrons results in Benzene becoming quite stable[1]. This is because the molecule is unaffected by addition reactions (which would disrupt the delocalisation of the electrons and affect the molecules stability)[2].
