2-butyne has higher boiling point than 2-butene because
A)2-butyne has stronger hydrogen bonds
B)2-butyne has stronger dipole dipole interactions
C)2-butyne has stronger london dispersion forces
D)2-butyne has triple bond which is harder to break
E)2-butyne has fewer hydrogens

Question

Quizplus · Accepted Answer

2-butyne has a linear structure due to its triple bond, which allows for more effective packing and thus stronger London dispersion forces compared to 2-butene, which has a more branched structure due to its double bond. This increased van der Waals interaction in 2-butyne leads to a higher boiling point.
