When 2-butyne is treate with H2/Lindlar's catalyst, compound X is produced as the major product and when treated with Na/liq. NH3 it produces Y as the major product Which of the following statements is correct ?
X will have higher dipole moment and higher boiling point than Y.
Y will have higher dipole moment and higher boiling point than X.
X will have lower dipole moment and lower boiling point than Y.
Y will have higher dipole momet and lower boiling point than X.
