B) LUMO of 1,3-butadiene and LUMO of ethylene
C) HOMO of 1,3-butadiene and HOMO of ethylene
D) LUMO of 1,3-butadiene and LUMO of 1,3-butadiene
E) HOMO of 1,3-butadiene and HOMO of 1,3-butadiene

Question

Quizplus · Accepted Answer

In a Diels-Alder reaction, which is the type of reaction that can form cyclohexene from 1,3-butadiene and ethylene, the HOMO (Highest Occupied Molecular Orbital) of the diene (1,3-butadiene) reacts with the LUMO (Lowest Unoccupied Molecular Orbital) of the dienophile (ethylene). This orbital interaction facilitates the formation of new sigma bonds in the cyclohexene product.
