What happens when polar molecules dissolve in water?
atoms donĀ“t get separated in glucose when you put it in water.a glucose crystal is different then for example a NaCl crystal.NaCl is an ionic crystal(it is made of Na+ and Cl- ions) and glucose is a molecule crystal made of molecules of glucose.so id will not dissolve like NaCl to ions it will dissolve to molecules of glucose.when we say something is dissolved it water it means that it is sorrounded by molecules of water.since water is polar,positive partial charges on H atoms and negative partial charge on O atom, partial negative charges on the oxygen of -OH glucose groups will attract partial positive charge on the -H of water causing it to be dissolved in water. water is more polar then other molecules(such as alcohols,eters…) and since water is not an ionic compound it will not break up in water.
