Question

Choose the most stable alkene
Options
A CH₃CH=CHCH₃
B CH₂=CH₂
C (CH₃)₂C=CHCH₃
Correct Answer
D (CH₃)₂CHCH₃
Correct Answer

Option C is the correct answer.

Detailed Explanation

Stability of alkenes increases with increased substitution on the double bond. (CH₃)₂C=CHCH₃ is a trisubstituted alkene, more stable than disubstituted (CH₃CH=CHCH₃) and monosubstituted (CH₂=CH₂).

Hint

More alkyl groups attached to the double bond = greater stability (hyperconjugation and inductive effects).
