Question : State two properties of carbon which lead to a very large number of carbon compounds. (b) Why does micelle formation take place when soap is added to water ? Why are micelles not formed when soap is added to ethanol ? |

Answer» Solution :(a) (i) Catenation (ii) TETRA valency . (b) It is because large number of molecular ions of soaps get AGGREGATED and form colloidal solution. Soap has hydrophobic tail (hydrocarbon ) which dissolves in hydrocarbon PART and hydrophilic part dissolves in water. Ethanol is non-polar solvent therefore micelles are not formed because hydrocarbon part gets ATTRACTED towards ethanol ionic end will . not dissolve in alcohol. |
