The correct Answer is:
A, C
`underset("But-1-yne")(HC -= C- CH_(2)- CH_(3)+ H_(2)O) overset(Hg^(2+),H^(+))to CH_(2)= underset(OH)underset(|)C- CH_(2)CH_(3) to CH_(3)- underset(O)underset(||)C- CH_(2)CH_(3)`
`underset("But-2-yne")(CH_(3)- C -= C- CH_(3)+ H_(2)O) overset(Hg^(2+),H^(+))to CH_(3)-CH= underset(O)underset(||)C-CH_(3) to CH_(3)CH_(2)- underset(O)underset(||)C- CH_(3)`
