Final answer:
Cyclohexane is more soluble in hexane because both are nonpolar and can interact through London dispersion forces, whereas glucose is polar and prefers polar solvents like water due to its ability to form hydrogen bonds.
Step-by-step explanation:
Among cyclohexane (C6H12) and glucose (C6H12O6), cyclohexane is likely to be more soluble in hexane (C6H14). This is because solubility often follows the principle of 'like dissolves like'. Hexane is a nonpolar solvent and cyclohexane, being a hydrocarbon with a similar nonpolar structure, will dissolve well in it. On the other hand, glucose has several hydroxyl groups (-OH) which are polar in nature, making it much more soluble in polar solvents like water rather than in nonpolar solvents like hexane. The solubility of a substance depends on its ability to form intermolecular forces with the solvent. Since cyclohexane and hexane can interact through London dispersion forces (a type of van der Waals force which is common in nonpolar compounds), they are compatible solutes. Glucose, due to its ability to form hydrogen bonds (which is a strong form of dipole-dipole interaction), has a higher affinity for solvents that can also participate in hydrogen bonding, such as water.
