On the basis of combustion distinguish between saturated and unsaturated organic compound |
| Answer» \tBASIS OF COMPARISONSATURATED HYDROCARBONSUNSATURATED HYDROCARBONSDescriptionSaturated hydrocarbons are compounds in which all hydrogen atoms and carbon atoms are bonded together with single bonds. Unsaturated hydrocarbons are compounds in which all hydrogen atoms and carbon atoms are bonded together by double or even triple bonds. ExamplesAlkanes are examples of saturated hydrocarbons Alkenes, alkynes and aromatic hydrocarbons are examples of unsaturated hydrocarbons. BurningSaturated hydrocarbons burn with a blue, non-sooty flame. Unsaturated hydrocarbons burn with a yellow sooty flame. Ration of Carbon To Hydrogen AtomsSaturated hydrocarbons have a less amount of carbon atoms bonded to a high number of hydrogen atoms. Unsaturated hydrocarbons have a high amount of carbon atoms bonded to fewer number of hydrogen atoms. SourceThey usually obtained from fossilized plant and animal materials. They are mainly obtained from plants (plant pigments, waxes, proteins, vegetable oil etc). ReactivitySaturated hydrocarbons are less reactive. Unsaturated hydrocarbons are more reactive when compared to saturated hydrocarbons. Reaction TypeThey undergo substitution reactions. They undergo addition reactions. ApplicationsSaturated hydrocarbons are mainly used for heating and cooking purposes. Unsaturated hydrocarbons are widely used as pesticides, fuel, paints and many other necessities. They are also used in many chemical reactions to synthesize other compounds. Water (Moisture) Production On CombustionSaturated hydrocarbons have more hydrogen content and therefore during combustion or heating, they produce more water (moisture). Unsaturated hydrocarbons have less hydrogen content and therefore during combustion or heating, they produce less water (moisture). SolubilityThey have low solubility in water. Unsaturated hydrocarbons are non-polar and therefore have low solubility in water. However, they are easier to dissolve in non-polar organic solvents such as benzene.\t | |
