**Question:** Which of the following could enter into H-bonding interactions with water? (Select all that apply.) **Options:** 1. **\[ \text{CH}_3\text{CH}_2\text{CH}_2\text{CH}_2\text{CH}_2\text{OH} \]** 2. A benzene ring with a nitrogen atom and bromine (Br) substituted on the ring. 3. ** \[ \text{CH}_3\text{CH}_2\text{CH}_2\text{CH}_2\text{CH}_3 \]** 4. ** \[ \text{CH}_3\text{CH}_2\text{HNCH(CH}_3\text{)}_2 \]** 5. None of the Above **Explanation for Graphs/Diagrams:** The second option shows a chemical structure diagram of a benzene ring with a nitrogen atom and a bromine atom attached to the ring, representing a possible substituent interaction. To determine if a compound can participate in hydrogen bonding with water, consider the presence of highly electronegative atoms such as oxygen or nitrogen directly bonded to hydrogen atoms.

Title: Intermolecular Hydrogen Bonding in Pure Compounds **Question:** In which of the following *pure* compounds would intermolecular hydrogen bonding be expected? *(Select all that apply.)* 1. **Compound A:** - Structure: \(\text{CH}_3\text{NCH}_2\text{CH}_2\text{CH}_2\text{CH}_3\) - Description: This structure contains a nitrogen atom bonded to hydrocarbon chains. 2. **Compound B:** - Structure: \(\text{CH}_3\text{CH}_2\text{CH}_2\text{CH}_2\text{CH}_2\text{OH}\) - Description: This structure contains a hydroxyl group (OH) at the end of a hydrocarbon chain. 3. **Compound C:** - Structure: \(\text{CH}_3\text{CH}_2\text{CH}_2\text{CH}_2\text{CH}_2\text{CH}_3\) - Description: This structure is a straight-chain hydrocarbon with no polar functional groups. 4. **Compound D:** - Structure: Cyclohexane ring with an amine group (\(\text{NH}\)) attached - Description: This structure contains a nitrogen atom in a cyclic structure with an additional hydrogen atom bonded to it. 5. **None of the Above** **Explanation:** - Compounds that can engage in intermolecular hydrogen bonding often contain N-H, O-H, or F-H bonds. These bonds create significant polarity and enable hydrogen bonding interactions with adjacent molecules. **Analysis of Compounds:** - **Compound A:** Contains a nitrogen but lacks an N-H bond required for hydrogen bonding. - **Compound B:** Contains an O-H group, which can participate in hydrogen bonding due to the high electronegativity of oxygen. - **Compound C:** Contains no N-H, O-H, or F-H bonds, which means it cannot participate in hydrogen bonding. - **Compound D:** Contains an N-H bond, which can participate in hydrogen bonding due to the electronegativity of nitrogen. The correct selections for compounds exhibiting intermolecular hydrogen bonding are Compound B and Compound D.
