The correct decreasing order of dipole moment among the following is?
2–Butyne > 1–Butyne > 1–butene
1–Butyne > 2–Butyne > 1–butene
1–Butyne > 1–butene > 2–Butyne
2–Butyne > 1–butene > 1–Butyne
Dipole moment of terminal Alkynes is more than the internal Alkynes. The symmetrical internal alkyne will have zero dipole moment
