Can someone draw the detailed reaction for the reaction of maleic anhydride and E,E-2,4-hexadien-1-ol. Also can...
Draw the endo and exo products for the reaction of 1,3(E)-pentadiene with maleic anhydride. Which is the major product?
diels alder reaction
Draw a structure for the exo product formed by cyclopentadiene and maleic anhydride. Because the exo form is more stable than the endo form, why is the endo product formed almost exclusively in this reaction? In addition to the main product, what are two side reactions that could occur in this experiment? The infrared spectrum of the adduct is given in this experiment. Interpret the principal peaks.

8) (E)-4-methylpenta-2,4-dien-1-ol and cyclopent-4-ene-1,3-dione can undergo a Diels Alder type reaction. First, draw the Huckel M.O. diagram for this system. Indicate which orbital is the HOMO and which is the LUMO for the diene and dienophile. Second, clearly sketch the cartoons that show which orbitals interact to allow cyclization. Based on your analysis, is this reaction allowed by heating? (15 points) (E)-4-methylpenta-2,4-dien-1-ol a OH + cyclopent-4-ene-1,3-dione
Can you also go into detail about drawing the HOMO and LUMO,
like how to know how many molecular orbitals there should be and
how many orbitals I should draw? Thanks!
LUH III. (16 pts). The Diels-Alder reaction of 1,3-cyclopentadiene with maleic anhydride (A) gives B as the major product. В a. (4 pts). Can product B be designated endo or exo? Explain b. (8 pts). Draw the highest occupied and lowest unoccupied molecular orbitals of the diene and of...
