Draw a valid structure corresponding to each of the following chemical names. 1. (1E,3Z)-4 tert- butoxy-1,4-difluoro-1-vinyloxybuta-1,3-dien-2-ol 2.. (R,E)-N-ally-N-sec-butyl-4-chloro-3-en-1-yn-3-amine
I need help interpreting the HNMR spectra. The compound is
(1E,4E)-1,5-bis(4-methylphenyl)penta-1,4-dien-3-one (C19H18O).
Please include where the hydrogen is attached (assignment). A
picture would be very helpful. Also please explain. Thank
you!!

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
