CHM 102 Alkenes: Structure, Bonding, and Geometrical Isomerism Objective Question

Question

Which alkene is generally more stable: cis-2-butene or trans-2-butene?
Options
A cis-2-butene
B trans-2-butene
Correct Answer
C Both are equally stable
D Stability depends on temperature
Correct Answer

Option B is the correct answer.

Detailed Explanation

Trans-2-butene is more stable than cis-2-butene due to less steric strain between the two methyl groups, which are farther apart in the trans isomer.

Hint

Bulky groups prefer to be opposite each other.
