Question

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 will turn green. Tools 4H Grading Include hydrogen atoms on non-carbon atoms Chirality is not graded.
