Example: predict the highest boiling point. question predict the boiling point order for the following compounds. explain your answer. a. 1,5-pentanediol b. 1-hexanol c. n-heptane solution all three compounds have similar formula masses: 104.1, 102.2, and 100.2 grams per mole, respectively. however, compound (a) (1,5-pentanediol) has two-oh groups, so it can form more hydrogen bonds than the others and can be expected to have the highest boiling point. compound (b) (1-hexanol) should be the next highest, since it is still an alcohol and can also form hydrogen bonds. finally, compound (c)(n-heptane) should have the lowest boiling point since it is an alkane and does not have any intermolecular forces other than dispersion forces. in fact, the actual boiling points are 242°c for 1,5-pentanediol, 157°c for 1-hexanol, and 98°c for n-heptane, so the prediction bears out. p feedback continue content attribution
