Lab Yield Problem

Hello, I am having a little trouble calculating a % yield for a lab practice problem. 0.8 mL of isoamyl alcohol and 1.6 mL of glacial acetic acid were mixed and 5 drops of sulfuric acid was added. 1.00 mL of ester was recoved. What was the % yield. I have used 0.81 g/mL and 88.15 g/mole for isoamyl alcohol. Could someone offer some help on how to calculate this? Thanks, Heath

retrosynthesis

provide a retrosynthetic and forward analysis for the following molecule, starting from commercially available compounds. The retrosynthesis should clearly identify the synthons and their synthetic equivalents. Also functional group interconversions and bond disconnections should be clearly indicated where needed. The forward synthesis should include reagents and conditions for each step. P.S arrow pushing mechanism are not required. thanks

IUPAC and SeAr reactions

Name by IUPAC, Number in order of reactivity (1 = fastest, 2 = next, etc.) each series to SEAr, Indicate with arrow(s) all the positions on each rng where appreciable SEAr reaction would occur. see attached problems.

Wavelength Max

Hello, Could you go through all the steps to solve this problem? Thanks, Heath Tyrian Purple is as the name suggests, purple. Suggest a (Lambda)max for Tyrian purple. Use the following correlation chart. (The chart is attached.)

Diels-Alder Reaction

C10H14(A) can only react with 2 equivalents of H2. C10H14 reacts with O3 to yield only one product (this product is attached.) Determine the two possible structures of (A). State which one could react with maleic anhydride and why.
