In the reaction


X and Y are:
  1. X = 1 - Butyne ; Y = 3 - Hexyne
  2. X = 2 - Butyne ; Y = 3 - Hexyne
  3. X = 2 - Butyne ; Y = 2 - Hexyne
  4. X = 1 - Butyne ; Y = 2 - Hexyne

Solution

Terminal alkynes on reaction with NaNH2/liq.NH3 results in the formation of sodium acetylides, and these sodium acetylides undergo nucleophilic substitution react with alkyl halides to form higher alkynes.
