Nonpolar organic molecules demonstrate ___________ solubility when placed in water?
Show answer Hide answer
Answer: B. Insoluble
Explanation
Nonpolar organic molecules lack partial electrical charges required to interact favorably with polar water molecules. Water molecules form extensive hydrogen bonds with one another, excluding nonpolar hydrophobic solutes. Consequently, nonpolar substances demonstrate extremely low solubility when introduced into aqueous environments. Polarity in chemistry refers to the unequal sharing of electrons across covalent chemical bonds. Hydrophobic interactions drive nonpolar molecules to aggregate together when placed in polar solvents. Common nonpolar organic molecules include hydrocarbons, fats, oils, and various organic solvents.
Cell membranes form stable lipid bilayers because hydrophobic fatty acid tails avoid surrounding cellular water. Oil spills in marine environments do not dissolve in water, creating persistent ecological pollution hazards. Pharmaceutical chemists modify drug polarity to ensure proper absorption and distribution through watery body fluids. Soluble is incorrect because nonpolar molecules cannot form favorable interactions with polar water solvents. Partially soluble applies mainly to amphipathic molecules possessing both polar and nonpolar functional regions. Depends upon condition is incorrect because standard nonpolar molecules remain universally insoluble in pure water.
