reaction

There are actuallly two isomeric 2,4-dinitrophenylhydrazones of 2-pentanone. Draw the structures of these isomers. (is it Z and E isomes?, see att. 1) 2-pentanone also forms a derivative on treatment with semicarbazide. Note that semicarbazine has two -NH2 groups that might react with the carbonyl of the ketone to form the se ...continues

Retrosynthesis 2

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 ...continues

Three compounds A, B and C all have the formula C5H10. A and B rapidly decolourise bromine dissolved in CH2CL2 but compound C is unreactive. Compound A reacts rapidly with acidified water and a tertiary alcohol D is formed; however compound B yields a secondary alcohol. (a) Draw a possible structure for each of A, B and C ...continues

Finding reagents

Hello, I am having some trouble finding the correct reagents to form the specified products. I have attached a pdf file with the products. There are 3 reagents involved. Here is what I have come up with so far but I am not sure they are correct. 1) BH3 in THF/H20 & H2O2 2) PBR3 via SN2 3) Li, Pentene & CH3I ...continues

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 ...continues

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.
