A hydrophobic substance placed in water will
A.clump together to minimize contact with water
B.dissolve completely
C.ionize into charged particles
D.form hydrogen bonds with water
Explanation
Core Concept
Nonpolar molecules cannot hydrogen-bond with water, so water molecules maximize their own bonding by excluding them — oil droplets coalesce. This hydrophobic effect drives membrane and protein folding.
Correct Answer
Aclump together to minimize contact with water
