Question
Differentiate between aromatic and aliphatic compounds.
✓
Answer
| Aromatic compounds: | Aliphatic compounds: |
| Aromatic compounds contain higher percentage of carbon. | Aliphatic compounds contain lower percentage of carbon. |
| They bum with sooty flame. | They bum with non$-$sooty flame. |
| They are cyclic compounds with alternate single and double bonds. | They are open chain compounds. |
| They are not attacked by normal oxidizing and reducing agents. | They are easily attacked by oxidizing and reducing agents. |
| They do not undergo addition reactions easily. They do not decolourise dilute alkaline aqueous $KMnO_4$ and $Br_2$ in $CCl_4,$ though double bonds appear in their structure. | Unsaturated aliphatic compounds undergo addition reactions easily. They decolourise dilute aqueous alkaline $KMnO_4$ and $Br_2$ in $CCl_4.$ |
| They prefer substitution reactions. | The saturated aliphatic compounds give substitution reactions. |
