SUMMARY

The discussion centers on determining which substance among glucose, graphite, sulfur, and lithium fluoride is most soluble in a nonpolar solvent. It is concluded that graphite, being a pure carbon element, is nonpolar and thus most likely to dissolve in nonpolar solvents. Lithium fluoride is ruled out due to its ionic nature, making it polar. Glucose is considered slightly polar due to its structure, while sulfur's solubility in nonpolar solvents is debated but is ultimately less favorable than that of graphite.

PREREQUISITES
  • Understanding of solubility principles in chemistry
  • Knowledge of polar and nonpolar molecular structures
  • Familiarity with ionic versus covalent bonding
  • Basic concepts of molecular symmetry
NEXT STEPS
  • Research the solubility rules for nonpolar solvents
  • Study the molecular structure of graphite and its properties
  • Explore the concept of polarity in organic compounds
  • Investigate the role of molecular symmetry in solubility
USEFUL FOR

Chemistry students, educators, and professionals interested in solubility principles and molecular interactions in nonpolar environments.

1. Which of the following substances is most likely to be soluble in a nonpolar solvent?

a. glucose
b. graphite
c. sulfur
d. lithium fluoride

Homework Equations



Is there a way to figure out which of the nonpolar molecules above would most likely be soluble using the structure of the substances?

The Attempt at a Solution


Lithium fluoride is ionic so it is polar so it cannot be it. Glucose does not appear to have perfect symmetry so I assumed that it was slightly polar. Sulfur and graphite are pure elements, and I don't understand why sulfur would more likely to be soluble in nonpolar solvent. Ksp seems useless here since we are not dealing with ionic compounds.

Except graphite is carbon and so are nonpolar solvents.
