Out of but-1-yne or but-1-ene which has higher dipole moment?

Explanation

`underset("But-1-yne")(H_(5)C_(2)-C-=C-H)` `" "`
Buy-1-tne has more dipole moment than but -1-ene because, `-=C-H` bond is more polar than = C-H bond Actually, the electronegativity of sp-C in alkyne is more than that of `sp^(2)-C` in alkene.
