Question

What type of weak interaction makes glucose soluble in water?

Answer 1

the three types of weak interactions are dipole-dipole, vanderwalls, and hydrogen. Water is H2O, meaning it has 2 hydrogen bonds. Glucose has many OH bonds, each of which can form a hydrogen bond. (A hydrogen bond is when a very electronegative molecule (usually water) attracts the electron circling hydrogen, so even though it's a covalent bond between the Oxygen and the hydrogen, there is a greater negative charge on the oxygen.) There will be many hydrogen bonds formed which will cause it to dissolve with relative ease.
