The validation about the presence of a “head and two tails” structure in the given substance has to be predicted. Concept introduction: The “head and two tails” model gives the orientation of groups in space. It has two parts, the head which is polar and the two tails, which are non-polar. The polar part of the model is soluble in water, so it is hydrophilic in nature. The non-polar part of the model is insoluble in water, so it is hydrophobic in nature.
