Carboxylic acids have higher than expected boiling points due to
dimeric associations involving hydrogen bonding. Several dimers of
3‑methylbutanoic acid (3‑methylbutyric acid) are shown where
proposed hydrogen bonding is represented by a dotted line.
Select the pair of compounds that show all of the expected
hydrogen bonds in a carboxylic acid dimer.

Carboxylic acids have higher than expected boiling points due to dimeric associations involving hydrogen bonding. The structure of 3-methylbutyric acid is shown below. Draw a second molecule of 3-methylbutyric acid - oriented in the most stable dimeric configuration with the other molecule of acid-and show the intermolecular hydrogen bonds. To indicate a hydrogen bond, draw a regular single bond between the atoms, then click on the "graded select" tool (the yellow highlighter) and click on the bond. A selected bond...
