What is non aromatic compound?
Answers
Answer:
A cyclic compound which doesn't necessitate a continuous form of overlapping ring of p orbitals need not be considered as aromatic or even anti aromatic and hence these are termed as nonaromatic or aliphatic.

Explanation:
The non-aromatic compounds without ring structure are termed aliphatic whereas those with a ring structure like cyclohexane are termed alicyclic. The aromatic hydrocarbons often consist of several fused rings as in case of benzopyrene.
Both classes of hydrocarbons occur naturally and notably in all kinds of oil and coal deposits. The aromatic compounds are also products of incomplete combustion of organic compounds which are released into the environment by both human activities and by natural causes. As compared to aromatic hydrocarbons are interesting not only because of its structure but also due to their mutagenic and carcinogenic properties.
Hydrocarbons are compounds composed of carbon and hydrogen alone, and they are classified into two main groups, aromatic and non-aromatic compounds. The aromatic hydrocarbons contain ring system with delocalized electron cloud while the non-aromatic hydrocarbons do not contain such a ring system. These include mainly the alkanes, which are saturated hydrocarbons, alkenes which contain one or more double bonds and finally the alkynes which contain one or more triple bonds.
Non-Aromatic Compounds Definition
A cyclic compound which doesn’t necessitate a continuous form of overlapping ring of p orbitals need not be considered as aromatic or even anti aromatic and hence these are termed as nonaromatic or aliphatic.
Non-aromatic compounds electronic energy is similar to that of its open-chain counterpart. Crude oil consists mainly of alkanes and large releases into the sea due to the wreckage of oil tankers have caused the death of many seabirds and other marine organisms because of their physical effects of oiling or smothering with these compounds.
Aromatic Compounds
The working knowledge of aromatic compounds has included the cyclic compounds containing conjugated double bonds with unusually large resonance energies. So aromatic compounds are those which meet the following criteria.
Structure must be cyclic containing some number of conjugated pi bonds
Within the ring, each atom must have un-hybridised p orbital and with sp2 hybridisation or sp hybridisation
Unhybridised p orbital must overlap to form a continuous ring of parallel orbitals
Most of the structure is planar or nearly planar for effective overlapping
Delocalization of the pi bond electrons over the ring must lower the electronic energy.
Compared to this the anti aromatic compound is one that refers to the first three criteria but delocalized pi electrons over the ring increase the electronic energy. The aromatic structures are more stable than their open-chain counterparts.
For example, 1, 3, 5 hexatriene is comparatively unstabler than the structure of benzene. The cyclobutadiene meets the first three criteria for a continuous ring of overlapping p orbitals but localization of the pi electrons increase the electronic energy.
Some aromatic compounds are shown below.

Nonaromatic chiral compounds are also resolved on polysaccharide based chiral stationary phase. Several nonaromatic compounds resolved on cellulose tri benzoate. The detection by a UV detector is often difficult and hence refractive index detector is used for enantiomer peak detection.
