    1>2>4>3 is reactivity order towards diels alder reaction....reverse its for energy barrier Explanation:- cyclopentadiene is most reactive towards diels alder reaction. Thiophene is least reactive as it is highly aromatic and doesnt undergo diels alder reaction easily Furan is less aromatic than pyrrole so it undergo diels alder reaction more easily than pyrrole. so more easily or more reactive is the compound...less is the energy barrier
