Answer:
D and E
Explanation:
According to Fajan's rules, a large ion size favours polarizability hence small ions are less polarizable.
Also, permanent dipole interaction leads to greater attraction between molecules than weak vanderwaals forces. Permanent dipoles generally lead to higher boiling and melting points.
Answer:
A: All other factors being the same, dispersion forces between linear molecules are greater than dispersion forces between molecules whose shapes are nearly spherical.
C: For molecules with varying molecular weights, the dispersion forces may not become stronger as the molecules become more polarizable.
D: The smaller the atom, the less polarizable it is
