Question

What is the primary reason lipids are not soluble in water?
Options
A They are too large
B They are polar
C Their structures are predominantly nonpolar/hydrophobic
Correct Answer
D They contain too many oxygen atoms
Correct Answer

Option C is the correct answer.

Detailed Explanation

Lipids are largely composed of hydrocarbon chains (C-H bonds), which are nonpolar and hydrophobic. Since water is a polar solvent, it cannot form favorable interactions with these nonpolar regions, making lipids insoluble.

Hint

Think 'like dissolves like.' Water is polar.
