उत्तर
| Saturated hydrocarbons | Unsaturated hydrocarbons | |
| 1. | Hydrocarbons having the carbon atoms linked to each other by single bonds are called saturated hydrocarbons. | Hydrocarbons having at least one carbon-carbon double or triple bond are called unsaturated hydrocarbons. |
| 2. | On burning, saturated hydrocarbons give a clean, blue flame. | On burning, unsaturated hydrocarbons give a yellow flame with lots of black smoke. |
| 3. | Saturated hydrocarbons do not decolourize bromine or iodine solutions. | Unsaturated hydrocarbons decolourize bromine or iodine solutions. |
| 4. | Saturated hydrocarbons are less reactive. | Unsaturated hydrocarbons are usually highly reactive. |
