Answers

Suppose you have two colorless molecular liquids, one boiling at $-84^{\circ} \mathrm{C},$ the other at $34^{\circ} \mathrm{C},$ 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 $-84^{\circ}$ both liquids have vapor pressures of 760 $\mathrm{mm} \mathrm{Hg}$ .
