About Aromatic Hydrocarbons(JEEMain,Class11th)

What is Aromatic Hydrocarbons?

Aromatic hydrocarbons are organic compounds that contain one or more benzene rings or similar aromatic ring structures. These compounds are known for their distinct aroma and possess unique chemical properties. They consist of carbon and hydrogen atoms arranged in cyclic structures with alternating single and double bonds. Aromatic hydrocarbons exhibit high stability due to the delocalization of electrons within the ring structure, known as aromaticity. They undergo substitution reactions rather than addition reactions, making them resistant to many typical organic reactions. Aromatic hydrocarbons have various applications in industries such as solvents, fuels, plastics, dyes, pharmaceuticals, and fragrances. They are widely used as raw materials and ingredients in the production of numerous consumer products.
