Let's again consider the structure of acetic acid, but this time add in partial charges for the oxygen and hydrogen atoms. ### Diagram Explanation The diagram shows the molecular structure of acetic acid with the following components: - A central carbon atom (C) double-bonded to an oxygen atom (O). This oxygen has a partial negative charge (δ⁻). - The same carbon is single-bonded to another oxygen atom (O), which also has a partial negative charge (δ⁻). This oxygen is further bonded to a hydrogen atom (H) with a partial positive charge (δ⁺). - The central carbon is also bonded to a methyl group (CH₃). ### Question How many sites on this molecule can be used to hydrogen bond to an H atom on an adjacent molecule? [Answer box not shown in the transcription]

Small carboxylic acids can dimerize by forming two hydrogen bonds between two molecules of the acid. Between which two pairs of atoms are hydrogen bonds found when two molecules of formic acid dimerize? **Diagram Explanation:** The image shows structural formulas for two formic acid molecules. Each molecule is depicted with an oxygen double-bonded to a carbon, which is bonded to an oxygen and hydrogen (carboxyl group), and is labeled with numbers: - First molecule: The oxygen at the top is labeled "5," the carbon is "2," and the hydroxyl group has hydrogen "1" and oxygen "3." - Second molecule: The oxygen at the top is labeled "10," the carbon is "7," and the hydroxyl group has hydrogen "6" and oxygen "9." **Question Options: (Select all that apply.)** - 9 and 5 - 6 and 5 - 4 and 10 - 1 and 10
