Question

how are micelles obtained give also mechanism

Answer 1

soaps are molecules in which the two ends have different properties one is hydrophilic that is it dissolve in water while the other end is hydrophobic that is it dissolves in hydrocarbons.when soap is at the surface of water the hydrophobic tail of soap will not be soluble in water and the soap will align along the surface of water with the ionic end in water and the hydrocarbon tail protruding out of water.inside water these molecules have a unique orientation that keeps the hydrocarbon portion out of water. this is achieved by forming clusters of molecules in which the hydrophobic tails are in the interior of the cluster and the ionic ends are on the surface of the cluster.This formation is called Michelle.

Answer 2

Answer:Micelles are formed by association of such molecule sin which both lyophilic and lyophobic parts are present . Such molecules are called surface active molecules .Example :Hydrocarbon chain in soap, sodium stearate C17 H35 COONa is lyophobic hydrophobic while - COONa is lyophilic or hydrophilic..The hydrocarbon tails are in the interior of the micelle and COO ions the surface . The grease stain absorbed in to the interior of the micelle which behaves like liquid hydrocarbon . As the strain is detached from the fabric , the dirt particles sticking to the strain are aslo removed.
