Question

But-2-yne and hydrogen (one mole each) are separately treated with (i) Pd/C and (ii) Na/liq. NH3 to give the products X and Y respectively. Pd/C X Y But-2-yne+H2 Na/Liq. NH3 Identify the incorrect statements. A. X and Y are stereoisomers. B. Dipole moment of X is zero C. Boiling point of X is higher than Y. D. X and Y react with O3/Zn + H2O to give different products. Choose the correct answer from the options given below :

(A) B and C only
(B) B and D only
