Question
Which alkene is generally more stable: cis-2-butene or trans-2-butene?
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.
