To explain why the anion \( \text{CH}_2 = \text{CH}^- \) is more basic than \( \text{HC} \equiv \text{C}^- \), we can analyze the acidity of the corresponding acids and the stability of the anions formed. ### Step-by-Step Solution: 1. **Identify the Structures**: - The anion \( \text{CH}_2 = \text{CH}^- \) corresponds to the alkene ethylene (ethene) where one hydrogen is removed, resulting in a double bond between the two carbon atoms. - The anion \( \text{HC} \equiv \text{C}^- \) corresponds to the alkyne acetylene where one hydrogen is removed, resulting in a triple bond between the two carbon atoms. ...
