Typing Answer is Mandatory! Explain the difference between cyclic hydrocarbons, aliphatic compounds, and aromatic compounds. Solution ALIPHATIC COMPOUNDS Compounds whose carbon atoms are linked in open chains, either straight or branched, rather than containing a benzene ring. Alkanes, alkenes, and alkynes are aliphatic compounds. For example methane, propane AROMATIC COMPOUND: Aromatic compounds, also known as arenes or aromatics, are chemical compounds that contain conjugated planar ring systems with delocalized pi electron clouds instead of discrete alternating single an double bonds. when they follow huckle rule they are called aromatic this  rule states that if a cyclic, planar molecule has 4n+2 ? electrons, it is considered aromatic. For example benzene, toluene CYCLIC HYDROCARBONS cyclic compounds are formed when carbon atoms bond together to form ring like structures. All the carbon carbon bonds are single bonds unlike aromatic compounds. For example cyclohexane. .
