Question

Quizplus · Accepted Answer

Hydroxyl groups (-OH) are present in carbohydrates, which are polar molecules and can form hydrogen bonds with water. Therefore, option D is the correct choice. Option A is incorrect because fats or lipids do not contain hydroxyl groups but instead contain ester groups (-COO-). Option B is also incorrect because carbohydrates are water-soluble due to the presence of hydroxyl groups. Option C is incorrect as polar carbohydrates will not dissolve in a nonpolar solvent.
