Question

Which of the following is the most stable alkene?
Options
A trans-3-hexene
Correct Answer
B cis-3-hexene
C 1-hexene
D (Z)-3-hexene
Correct Answer

Option A is the correct answer.

Detailed Explanation

Trans alkenes are generally more stable than cis alkenes due to less steric strain. trans-3-hexene is the most stable among the options because it is a trans internal alkene (disubstituted) with the bulky groups on opposite sides. 1-hexene is a terminal alkene and less substituted.

Hint

Which isomer is more stable: trans or cis?
