Question

Is cyclohexane aromatic?

Answer 1

We need to know what are cyclic compounds and the concept of aromaticity. A cyclic compound is one in which one or more series of atoms in the compound are linked to create a ring. Rings can range in size from three to many atoms, and they can include all carbon atoms, none carbon atoms (inorganic cyclic compounds), or mixed carbon and non-carbon atoms (heterocyclic compounds).

Complete answer:
As a result of the ring size, the bond order of connections between ring atoms, and their configurations inside rings (which can range from totally saturated to having various numbers of multiple bonds between ring atoms), carbocyclic and heterocyclic compounds can be aromatic or non-aromatic. Aromaticity is a word used in organic chemistry to characterize a cyclic (ring-shaped), planar (flat) molecule that has exceptional stability when compared to alternative geometric or connective configurations of the same set of atoms. Because of their stability, aromatic molecules are extremely difficult to break apart and react with other compounds. Aliphatic compounds are organic compounds that are not aromatic—they may be cyclic, but only aromatic rings have particular stability (low reactivity).
Organic compounds are classified as open and closed chain compounds. There are also homocyclic and heterocyclic compounds in a closed chain. There are two types of homocyclic molecules: alicyclic and aromatic chemicals. Only single bonds are permitted in alicyclic compounds, but in the aromatic category, the ring of carbon atoms includes alternate single and double bonds (i.e., conjugated double bonds).
There are no double or triple-bond carbon atoms in cyclohexane since there are only sigma bonds and no pi bonds. As a result, it lacks pi electrons. As a result, it does not adhere to Huckel's criterion and is hence not aromatic.

Note:
It must be noted that cyclic compounds can be aromatic or non-aromatic; benzene is an example of an aromatic cyclic chemical, but cyclohexane is not. Cyclohexane, having the chemical formula${C_6}{H_{12}}$, is a cycloalkane. Non-polar solvent cyclohexane is a colorless, flammable liquid, Cyclohexane smells strong like cleaning products (in which it is sometimes used). Cyclohexane is primarily utilized in the commercial manufacture of adipic acid and caprolactam, two precursors of nylon.
