What is the correct relative stability order of the different types of dienes? — GOC and Organic Chemistry Basics Chemistry Question

💡 Solution & Explanation

Conjugated dienes have overlapping p-orbitals allowing delocalization of $\pi$ electrons across the system, conferring maximum stability. Isolated dienes lack this extended delocalization. Cumulated dienes have adjacent $\pi$ bonds that are perpendicular, causing strain and making them the least stable.
