15. Write yes or no by each of the following classes or compounds to indicate
whether compounds of that class generally form hydrogen bonds between their
Carboxylic acid (RCOOH)
16. If compounds of a single class can form hydrogen bonds between their own
molecules, then the boiling point of that compound is (lower) (higher) than the
alkane of similar molecular weight. Compounds with one particular functional
group are able to form two hydrogen bonds between a pair of its molecules; this
functional group is _______________. Thus, carboxylic acids tend to have a
very (high) (low) boiling point, compared to alkanes of similar molecular weight.
As a result, carboxylic acids are usually (solid) (liquid).
17. The boiling points of ethers, aldehydes, ketones, and esters are (about the same
as) (more than) the boiling points of alkanes of similar molecular weight.
18. The boiling points of alcohols, phenols, amines, amides, and carboxylic acids are
(lower) (higher) than the boiling points of alkanes of similar molecular weight.
