Question
Why do trans isomers of alkenes have lower boiling points than cis isomers?
Correct Answer
Option C is the correct answer.
Detailed Explanation
Cis isomers are more polar (have a net dipole moment) than trans isomers, which are often nonpolar or less polar. The stronger dipole-dipole interactions in cis isomers lead to higher boiling points.
Hint
How does polarity affect boiling points of cis and trans isomers?
