Which common structural feature of vitamin E and vitamin K₁ best accounts for the greater solubility of these molecules in organic solvents than water?

Question

Quizplus · Accepted Answer

The 4 isoprene units in both vitamin E and vitamin K contribute to their greater solubility in organic solvents. Isoprene units are nonpolar and hydrophobic, which makes these molecules more soluble in nonpolar organic solvents than in water, which is polar. The presence of aromatic rings (A) or oxygen atoms (B) does not necessarily increase solubility in organic solvents. The quinone/hydroquinone unit (D) is not present in vitamin E or vitamin K.
