When Water and Hydrophobic Molecules are Mixed All of the Following

Question

When water and hydrophobic molecules are mixed all of the following are true except:
A) The hydrophobic molecules aggregate
B) The free energy of dissolving molecules is unfavorable
C) -T$\Delta$ S becomes negative
D) Water's hydrogen-bonded interactions are disrupted
E) All of the above are true

Accepted Answer

The correct answer is E because all of the statements are true. When water and hydrophobic molecules are mixed, the hydrophobic molecules aggregate to minimize their contact with water. The free energy of dissolving the molecules is unfavorable because the hydrophobic molecules are not soluble in water. The -TF1F1F1S1F1F1F10S becomes negative because the entropy of the system increases when the hydrophobic molecules aggregate. Water's hydrogen-bonded interactions are disrupted because the hydrophobic molecules interfere with the formation of hydrogen bonds between water molecules.
