Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Molecules that are nonpolar and have no charged regions are repelled by water, or they stay away from water. We call those ____ molecules
A
electrostatic
B
hydrophilic
C
hydrostatic
D
hydrophobic
Explanation: 

Detailed explanation-1: -Hydrophobic liquids, such as oil, will separate from water. Hydrophobic molecules are usually nonpolar, meaning the atoms that make the molecule do not produce a static electric field. In polar molecules these opposite regions of electrical energy attract to water molecules.

Detailed explanation-2: -5 Ions and ionic compounds are hydrophilic. So are polar molecules. In contrast, nonpolar molecules are hydrophobic.

Detailed explanation-3: -Nonpolar molecules that repel the water molecules are said to be hydrophobic; molecules forming ionic or a hydrogen bond with the water molecule are said to be hydrophilic.

Detailed explanation-4: -The hydrophobic effect describes the energetic preference of nonpolar molecular surfaces to interact with other nonpolar molecular surfaces and thereby to displace water molecules from the interacting surfaces. The hydrophobic effect is due to both enthalpic and entropic effects.

Detailed explanation-5: -Hydrophobic Means “Fear of Water": Hydrophobic molecules repel water because they are generally non-polar molecules. As water is a polar molecule, hydrophobic molecules tend to interact with each other instead of with water.
