Adding surfactants in non polar solvent, the micelles structure will look like (a) (b) (c) (d)

Options

Correct answer

C. a

Step-by-step solution

Micelles are formed by self-assembly of amphiphilic molecules. The structures contain hydrophilic/polar region (head) and hydrophobic/nonpolar region (tail). Micelles are formed in aqueous solution whereby the polar region faces the outside surface of the micelle and the nonpolar region forms the core. Non-polar part will interact with non-polar solvent.
