Question

1. Compare and contrast hydrophobic effect with micellar catalysis in a reaction.

Answer 1

Hydrophobic effect: In simple words ,it is exclusion of non polar substances from an aqueous solution .

Micellar catalysis: When amphophilic are distributed in water , their hydrophobic part keep away from

water and forms aggregation of molecules , that is called micelle.

Amphophilic*= a compound consisting of molecules having a polar water soluble group in water and

insoluble hydrocardhychain also.

Hydrophobic effect with Micellar catalysis:

Hydrophobic effect leads to Micelle formation .

The tendency of amphophilic compounds to form micelle is a result of hydrophobic effect . The micelle catalysis

is due to the driving hydrophobic forces which further depends upon the length scale of dependence of aqueous

solvation .

Thus miceller catalysis happens because of hydrophobic effect as it that part of compound that is not soluble in

aqueous solution and that results in a miccele formation.Examples are like the miceller catalysis in organic solvents

like oil and fatty acids .
