When certain substances dissolve, the solution gets colder. This type of dissolving process is endothermic. In endothermic dissolving
Slightly negative near the oxygen atom and slightly positive near the hydrogen atoms
The water molecules cause the sucrose molecules to separate from one another
Share electrons
More energy is used to pull the solute apart than is released when water molecules bond to the solute.
To dissolve in alcohol not as well as in water
Oxygen has a stronger attraction for electrons than hydrogen
Polar water molecules attract the opposite polar areas of the sucrose molecules
The positive area of one water molecule is attracted to the negative area of another
The atoms in a water molecule are held together by covalent bonds. This means that the bonded atoms

Alcohol molecules are not as polar as water molecules. If you mixed sucrose in alcohol you might expect the sucrose
