Intermolecular forces?
-
a) of these ions K+, Na+, Be2+ which has the largest heat of hydration and which has the smallest? b) KNO3 and NaNO3 which as the strongest intermolecular force? c)PCl3 and Xe which has the strongest intermolecular force? I am guessing a) Be2+ would have the largest and K+ would have the smallest b) NaNO3 c) Xe because there is no force to pull?

Answer:
There are three intermolecular forces - Van der Waals (the weakest), Permanent Dipoles and then hydrogen bonds (the strongest). a) Correct b) KNO3 because K is less electronegative than Na, resulting in a larger attraction c) There is van der waals forces in Xe, which are the weakest intermolecular forces. In PCl3 there is a permanent dipole, because one of the elements (Chlorine) has more electronegativity, and this results in a permanent dipole - which is stronger than van der waals forces!
