Question
Which alkene is most stable?
Correct Answer
Option D is the correct answer.
Detailed Explanation
Stability increases with alkyl substitution: tetrasubstituted > trisubstituted > disubstituted > monosubstituted > ethene. 2-Methyl-2-butene is trisubstituted and very stable.
Hint
More alkyl groups on the double bond = more stability.
