Which hydrocarbons have six-membered carbon rings and delocalized electrons?
aromatic hydrocarbons
Aromatic hydrocarbons are a class of organic compounds that contain a cyclic arrangement of atoms that includes one or more rings of carbon atoms with alternating double bonds. This arrangement of atoms gives aromatic hydrocarbons unique chemical and physical properties.
Aromatic hydrocarbons are also known as arenes or aromatics and are comprised of benzene and related compounds. These compounds generally have a pleasant odor and are found in many plant and animal tissues, as well as in crude oil and coal tar.
Some common examples of aromatic hydrocarbons include benzene, toluene, naphthalene, and anthracene. Aromatic hydrocarbons are used in a variety of applications, including as solvents, fuels, and in the production of plastics and pharmaceuticals.
However, many aromatic hydrocarbons are toxic and can pose health risks to humans and the environment. Benzene, for example, is a known carcinogen and exposure to high levels can lead to serious health issues such as leukemia and other blood disorders.
In summary, aromatic hydrocarbons are a class of organic compounds that contain a cyclic arrangement of atoms and have unique chemical and physical properties. While they have many useful applications, they also pose health and environmental risks.
