Chapter 11, Problem 20E

True or false:

a. For molecules with similar molecular weights, the dispersion forces become stronger as the molecules become more polarizable.
b. For the noble gases the dispersion forces decrease while the boiling points increase as you go down the column in the periodic table.
c. In terms of the total attractive forces for a given substance, dipole ---dipole interactions, when present, ore always greater than dispersion forces,
d. All other factor being the same, dispersion forces between linear molecules are greater than those between molecules whose shapes are nearly spherical.
e. The larger the atom, the more polarizable it is.
