4a. A Diels-Alder reaction occurs when the highest occupied molecular orbital (HOMO) of the diene interacts with the lowest unoccupied molecular orbital (LUMO) of the dienophile. Fill the molecular orbital diagrams given to identify the HOMO and LUMO and show how the orbitals interact to give the product

Give the product of the following reaction: Draw the HOMO of butadiene and the LUMO of ethene (ethylene); include orbital phases. An unknown starting material underwent an S_n^2 reaction with NaBr to give the following products. Based on the mass spectrum below, what is the unknown starting material? (1)

5. Molecular orbitals are formed by the overlap of atomic orbitals. Thus, n atomic orbitals can combine (overlap) to form n molecular orbitals. In 1,3-butadiene there are four atomic p orbitals which can combine to form four 7 molecular orbitals. In ethene there are two atomic p orbitals which can combine to form two y molecular orbitals. The drawings below show the different ways in which the p orbitals of ethene and 1,3- butadiene can be combined to form the...
