Which of the following has higher dipole moment and why?
But -1- ene or But -1- yne

Explanation

Their strcutures are : `H_(3) underset("1-Butyne")(C-CH_(2) - C-=C-H)`
In 1-Butyne , each triply bonded C-atom is sp -hybridized whereas in 1-Butene, each doubly bonded
C-atom is `sp^(2)` -hybridized . Hence 1-Butyne has larger dipole moment because the electronegativity of
sp-C is more than that of `sp^(2) - C`
