To solve the problem, we need to determine the product (X) formed when 2-butyne (H₃C-C≡C-CH₃) is treated with sodium (Na) in liquid ammonia (NH₃). This reaction is known as the Birch reduction, which converts alkynes into trans alkenes. ### Step-by-Step Solution: 1. **Identify the Reactant**: The given compound is 2-butyne, which has the structure H₃C-C≡C-CH₃. It is an alkyne because it contains a triple bond between two carbon atoms. 2. **Understand the Reaction Conditions**: The reaction involves sodium metal and liquid ammonia. This combination is characteristic of the Birch reduction, which is used to convert alkynes to alkenes. ...
