Question

Sugar is soluble in water due to:

• A. high solvation energy.
• B. ionic character of sugar.
• C. high dipole moment of water.
• D. hydrogen bond formation with water.

Answer 1

The correct option is D hydrogen bond formation with water.

The bond between the oxygen and hydrogen atoms ($O–H$ bond) in sugar (sucrose) gives the oxygen a slight negative charge and the hydrogen a slight positive charge.Sucrose is a polar molecule.
