Explanation / Answer

3. Glucose or salts or acids which can have strong hydrogen bonding with water dissolve in it. However, hydrocarbons which cannot form hydrogen bond or which does not dissociate in water is insoluble. Hence, only C5H10 is insoluble all other are water soluble.

Na2SO4 is highly soluble in water

C6H12O6 is a chemical formula for glucose which is highly soluble in water

O2 or oxygen is also water soluble

N2H4, hydrazine is also soluble in water

C5H10, is a non-polar hydrocarbon which is not soluble in water (insoluble)

HNO3 is highly soluble in water.
