?The sp-hybrid carbon atoms of the triple-bond render alkynes more electrophilic than similarly substituted alkenes. As a result, alkynes sometimes undergo addition reactions initiated by bonding to a nucleophile.
  • Alkyne gets reduced to alkene in the presence of sodium, liquid ammonia and NaNH2.
