A) a zwitterion.
B) amphipathic.
C) polar.
D) nonpolar.

Question

Quizplus · Accepted Answer

A molecule with both hydrophobic (water-repelling) and hydrophilic (water-loving) properties is best described as amphipathic. This is because it has two distinct properties that create a polarity within the molecule, with one end being attracted to water and the other being repelled by it. The other answer choices do not adequately describe this type of molecule. Zwitterions are molecules with both positive and negative charges but do not necessarily have hydrophobic properties. Polar molecules have a partial positive and negative charge but may not have hydrophobic properties. Nonpolar molecules lack a charge and are typically hydrophobic but do not have hydrophilic properties.
