both ionic end and carbon chain are in the interior of the cluster
both ionic end and carbon chain are on the exterior of the Cluster
Solution
the ionic end of soap is on the surface of the cluster while the carbon chain is in the interior of the cluster
Explanation -
Soaps are molecules in which the two ends have differing properties, one is hydrophilic, that is, it interacts with water, while the other end is hydrophobic, that is, it interacts with hydrocarbons. 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 are called a micelle.
