Question

While synthesizing a new blue pigment, a chemist notices that the new compound accumulates between an aqueous (water) environment and a hydrophobic environment. When added to a mixture of oil and water, the pigment creates a blue ring around the droplets of oil. Which of the following statements best describes this new pigment?

A. The pigment is amphipathic, having polar and nonpolar regions.
B. The pigment is probably hydrophobic and is attempting to bond with the oil.
C. The pigment is hydrophilic and will not form hydrophobic bonds with the oil.
D. The pigment is a polar molecule and is forming hydrogen bonds with both the water and oil molecules.
E. The pigment is neither polar or nonpolar, but is apolar.

Answer 1

Answer: C

Step-by-step explanation:

Does not build hydrophobic bonds with oil because it is hydrophilic.

Hope it helps :)
