Differentiate between aromatic and aliphatic compounds.

1.	Differentiate between aromatic and aliphatic compounds.
Answer» Aromatic compounds: Aromatic compounds contain higher percentage of carbon. They bum with sooty flame. They are cyclic compounds with alternate single and double bonds. They are not attacked by normal oxidizing and reducing agents. They do not undergo addition reactions easily. They do not decolourise dilute alkaline aqueous KMnO₄ and Br₂ in CCl₄ , though double bonds appear in their structure. They prefer substitution reactions. Aliphatic compounds: Aliphatic compounds contain lower percentage of carbon. They bum with non-sooty flame. They are open chain compounds. They are easily attacked by oxidizing and reducing agents. Unsaturated aliphatic compounds undergo addition reactions easily. They decolourise dilute aqueous alkaline KMnO and Br₂ in CCl₄ . The saturated aliphatic compounds give substitution reactions.
