Distinguishing the Aromatic and non Aromatic compounds?

Aromatic compounds

• Are Cyclic Structure
• Planar [ all atoms of cyclic ring in SP2 or SP Hybridization ]
• Satisfy Huckle`s rule [ 4n + 2  = pi ]
• Resonance stabilized
• Negative Bromine test [ Test for Unsaturation ]
• Dry Heating test burn with sooty flame

e.g.- Benzene, Phenol, Aniline, Naphthalene etc

Non Aromatic compounds

• May or may not Cyclic Structure
• May or may not Planar 
• Not Satisfy Huckle`s rule [ 4n + 2  = pi ]
• May or may not Resonance stabilized
• May or may not Positive Bromine test [ Test for Unsaturation ]
• Dry Heating test burn with non sooty flame

e.g.- Cyclopentane, Cyclobutene, Hexane etc
