Why is NH3 soluble in H20 but NCl3 is not?
storchak [24]
NH3 is soluble in water because it has the same amount of intermolecular forces as water. NH3 is a polar molecule and water  is a polar molecule so they dissolve each other. NCl3 does not dissolve in water because it is a nonpolar molecule which is different with water. NCl3 is nonpolar due to the difference in electronegativities between 3 atoms of Cl and 1 atom if N2.
