why is sugar more soluble in water than in canola oil???? in english please ive asked this question and it didn't make sense
Water molecules have a higher electric polarity than oil.
Sugar dissolves in water because energy is given off when the slightly polar sucrose molecules form intermolecular bonds with the polar water molecules.
Sucrose is a polar molecule. The polar water molecules attract the negative and positive areas on the polar sucrose molecules which makes sucrose dissolve in water. A nonpolar substance like mineral oil does not dissolve a polar substance like sucrose.
