Foreach statement that is not correct, modify the statement sothat it is correct. (a) The higher-boiling liquid has greatertotal intermolecular forces than the lower-boiling liquid. (b)The lower-boiling liquid must consist of nonpolar molecules.(c) The lower-boiling liquid has a lower molecular weightthan the higher-boiling liquid. (d) The two liquids have identicalvapor pressures at their normal boiling points. (e) At-84 °C both liquids have vapor pressures of 760 mm Hg.

Question
Suppose you have two colorless molecular liquids, one boiling
at -84 °C, the other at 34 °C, and both at atmospheric
pressure. Which of the following statements is correct? For
each statement that is not correct, modify the statement so
that it is correct. (a) The higher-boiling liquid has greater
total intermolecular forces than the lower-boiling liquid. (b)
The lower-boiling liquid must consist of nonpolar molecules.
(c) The lower-boiling liquid has a lower molecular weight
than the higher-boiling liquid. (d) The two liquids have identical
vapor pressures at their normal boiling points. (e) At
-84 °C both liquids have vapor pressures of 760 mm Hg.
