The correct answer is D: Lyotropic liquid crystal. Soap molecules are amphiphilic, having a hydrophilic head and hydrophobic tail. When dissolved in water at appropriate concentrations, they self-assemble into ordered structures like micelles and lamellar phases, forming a lyotropic liquid crystal.
A.Metallotropic liquid crystal
B.Thermotropic liquid crystal
C.Homogeneous solution
D.Lyotropic liquid crystal✓ Correct
Explanation
Soap molecules are amphiphilic, having a hydrophilic head and hydrophobic tail. When dissolved in water at appropriate concentrations, they self-assemble into ordered structures like micelles and lamellar phases, forming a lyotropic liquid crystal. Lyotropic liquid crystals are formed by amphiphilic molecules in a solvent (typically water), with their structure depending on concentration. Thermotropic liquid crystals depend on temperature only and are formed by pure compounds, not solutions.
