draw two structures of azo dyes that do not have the same color of methyl orange.
draw two structures of azo dyes that do not have the same color of methyl orange.
name and CHEM DRAW the structures of three well known azo dyes and write a short paragraph about their application. please use Scifinder as a resource. :)
question 3 please
2. (3 Points) of the following 3 azo dyes, one is yellow, one is purple, and one is green. Indicate which dye is which color and explain your reasoning. OOH Hoo OH ON SO H HO NO2 но Azo Dye A Azo Dye B Azo Dye C 3. (3 Points) Draw the starting materials (diazonium salt and aromatic nucleophile) that would be required to make Azo Dye A from question 2.

EXPERIMENT 8: SUPPLEMENTARY LAB QUESTIONS 1. Would you expect benzoic acid or anisole to be a more effective coupling reagent? Why? Anisole would be more effective coupling agent reagents than benzoic acid because anisole has o-cH₃ an electron donating group whereas benzoic acid have a 2-oh group attached to the benzene ring that acts as electron withdrawing group. 2. Most diazo coupling reactions do not work well in acidic solutions. Explain. 3....
250 Experiments 2. A solution causes a yellow color with thymol blue, an orange color with methyl orange, a color with methyl red, and a yellow color with bromthymol blue. The pH must le between and The estimated pH is_ b. A solution causes a yellow color with thymol blue, yellow colors with both methylona and methyl red, and a green color with bromthymol blue. The pH must lie between and The estimated pH is
EXERCISE 17.8: The structures of two common tracking dyes are given below. Under identical conditions, which dye will migrate farther in a gel electropherogram? Defend your answer. NH7 NH2 H,N NH, (HC)2N N(CH)2 Pararosalin Methyl violet

Based on your endpoint indicated by the methyl orange and the equivalence points determined by the titration curve for your Na2CO3 titration using the pH electrode, which of the following are true? (Select all that apply.) The methyl orange was not necessary since the pH change indicated the second equivalence point. The methyl orange was not necessary since the pH change indicated the first equivalence point. The endpoint and the second equivalence point occurred together. The endpoint and the first...
What structural characteristics give dyes their color? List two examples that fit this trend.
U U DEU Methyl violet to be in an acidic solution? tretet qellow at color do you expect methyl violet to be in a basic solution? Orange Blue POST-LAB QUESTIONS PART A 1. Why did the color change when you added the concentrated HCl to the CoCl2-6 H2O2 e 2. Why did the color change when you diluted the solution? 3. Is Reaction 1 endothermic or exothermic? Explain your choice. PART B 4. Explain why the reagent you used in...
Draw two constitutional isomers that share the molecular formula C2H6O. Your structures will have the same molecular formula but will have different connectivities.
