In chemistry, aromaticity is a property of cyclic, planar structures with a ring of resonance bonds that gives increased stability compared to other geometric or connective arrangements with the same set of atoms.
These molecules are very stable and do not break apart quickly to react with other substances.
1-Hexene is an organic compound with the formula C₆H₁₂. It is not an aromatic compound.
It is an alkene that is classified in industry as higher olefin and an alpha-olefin, the latter term meaning that the double bond is located at the alpha position, endowing the compound with higher reactivity and thus useful chemical properties.
Formula-
Boiling point- 63.85 °C
Density- 673 kg/m³
Benzene is an aromatic compound, as the C-C bonds formed in the ring are not exactly single or double, rather they are of intermediate length.
Aromatic compounds are divided into two categories: benzenoids (one containing benzene ring) and non-benzenoids (those not containing benzene ring), provided they follow Huckel rule.
Naphthalene is an organic compound with formula C₁₀H₈. It is the simplest polycyclic aromatic hydrocarbon and is a white crystalline solid with a characteristic odor that is detectable at concentrations as low as 0.08 ppm by mass.
