Molecules that are soluble in water are ________ and molecules that are insoluble in water are ________.

Question

Quizplus · Accepted Answer

Molecules that are soluble in water (such as salts, sugars, and polar molecules) are hydrophilic, meaning they interact with water and can dissolve in it. Conversely, molecules that are insoluble in water (such as oils, fats, and nonpolar molecules) are hydrophobic, meaning they tend to avoid interaction with water and do not dissolve in it. Choice D correctly identifies these terms. Choices A and B are incorrect because endergonic and exergonic refer to energy changes in chemical reactions, not solubility properties of molecules. Choice C is almost correct, but reverses the definitions of hydrophobic and hydrophilic.
