• A. Polar at outer surface and non-polar at inner surface
• B. Polar at inner surface and non-polar at outer surface
• C. Distributed over all the surface
• D. Are present in the surface only

Answer 1

The correct option is A Polar at outer surface and non-polar at inner surface

Micelles are the clusters formed by the association of colloids. They are formed by lyophillic and lyophobic groups. As the concentration is increased the lyophobic parts receding away from, the solvent approach each other and form a duster, the lyophobic ends are in the interior lyophilic groups projecting outward in contact with the solvent.
