Position of non-polar and polar parts in micelle is

Options

A. polar at outer surface but non-polar at inner surface
B. polar at inner surface but non-polar at outer surface
C. distributed all over the surface
D. present in the surface only

Answer

A

Explanation

Micelles are the clusters formed by the association of colloids. They are formed by lyophilic and lyophobic groups. As the concentration increases, the lyophobic parts receding away from the solvent approach each (non-polar part) other and form a cluster, the lyophobic ends are in the interior, lyophilic groups (polar part) projecting outward in contact with the solvent.
