Aromatic rings or arenes are a type of hydrocarbon that possess a unique ring structure called benzene. These arenes are composed of carbon and hydrogen atoms, bonded together in a particular pattern. This ring structure is characterized by a high level of stability, which makes it resistant to many chemical reactions that other hydrocarbons would undergo. Because of this, aromatic rings and compounds have a variety of applications in various fields, including pharmaceuticals, dyes, and perfumes.What is the number of aromatic rings present in the molecule?
