Question
Why does cis-2-butene have a higher boiling point than trans-2-butene?
✓

Answer

cis-2-Butene is more polar than trans-2-butene, therefore, it has more van der Waals’ forces of attraction, hence higher boiling point due to higher dipole moment, whereas trans-2-butene has zero dipole moment.
