Question
Which of the following compounds is most stable?
Correct Answer
Option B is the correct answer.
Detailed Explanation
Alkene stability increases with the number of alkyl substituents on the double bond (more substituted alkenes are more stable). 2,3-Dimethyl-1-butene is a disubstituted alkene, more stable than ethylene (unsubstituted), propylene (monosubstituted), and 2-butene (disubstituted but less substituted than 2,3-dimethyl-1-butene).
Hint
How does substitution affect alkene stability?
