Question

Which of the following would be expected to be the most soluble in water?

A) Polar molecule.
B) Nonpolar molecule.
C) Large hydrophobic molecule.
D) Small hydrophilic molecule.

Answer 1

The most soluble substance in water would be a small hydrophilic molecule, such as methanol (CH3OH). Nonpolar molecules, like octane (C8H18), are hydrophobic and do not dissolve well in water.

Step-by-step explanation:

Water is considered a polar solvent, and substances that are polar or ionic will dissolve in it. The most soluble substance in water would be a small hydrophilic molecule. Examples of small hydrophilic molecules include methanol (CH3OH). On the other hand, nonpolar molecules, such as octane (C8H18), are hydrophobic and do not dissolve well in water.
