1-Luminol is insoluble in water, BUT it does dissolve in aqueous NaOH. Explain. 2-Discuss the mechanism for the chemiluminescence of luminol.
Find three examples of compounds (other than luminol) that undergo chemiluminescence upon a chemical reaction. Draw their structures Please.
1. After filtering your final product, you find that your product is still wet, but you proceed to take a melting point anyways. The literature melting point of luminol is 319 °C. What do you expect the melting point of your luminol to be? What would you expect the yield to be? Would it be an accurate yield? 2. While going to conduct the chemiluminescence test, you forgot to dilute Solution A. What do expect the effect of your chemiluminescence...

Organic Chemistry Post Lab Questions for the Synthesis of Luminol
synthesis of Luminol from 3-nitrophthalic acid and hydrazide
1. A. Draw a well-labeled diagram which shows the singlet state, singlet excited state and the triplet state in a energy level diagram. Show the spin of electrons in each of these states. B. Show transitions in your diagram and label the radiative processes as either phosphorescence or fluorescence C. Discuss which of these are "allowed "transitions and which are "forbidden" transitions....
Compare and contract chemiluminescence, fluorescence, phosphorescence, bioluminescence, and triboluminescence.
The chemical 5-amino-2,3-dihydro-1,4-phthalazinedione, better known as luminol, is used by forensic scientists in analyzing crime scenes for the presence of washed-away blood. Luminol is so sensitive that it can detect blood that has been diluted 10,000 times. A basic solution of luminol is often sprayed onto surfaces that are suspected of containing minute amounts of blood. Luminol has a molecular weight of 177 g/mol. Part A The forensic technician at a crime scene has just prepared a luminol stock solution by adding 16.0...
2. A structure of Luminol is shown with all functional groups protonated and their pka labeled. Use words and structures to answer a and b. Luminol pke 2 9 a. Acetic acid was added at the end of the reduction step to obtain a pH of - 3-4.2pts i. Draw the structure of the luminol at pH 3. ii. Refering to the structure in a.i.), explain why the luminol precipitates from the aqueous solution at this pH. NH₂ NH N-H...
The forensic technician at a crime scene has just prepared a luminol stock solution by adding 13.0 g of luminol into a total volume of 75.0 mL of H2O. Luminol has a molecular weight of 177 g/mol. What is the molarity of the stock solution of luminol? Before investigating the scene, the technician must dilute the luminol solution to a concentration of 4.00×10−2 M . The diluted solution is then placed in a spray bottle for application on the desired...
