4. Draw missing resonance structures in the boxes below Curved arrows are not required. H Organic compounds can serve as Bronsted-Lowry acid in water. The degree of deprotonation in aqueous solution depends 5. Acetaminophen is the active ingredient in Tylenol® and is insoluble in water. However, its deprotonated form is soluble in on the strength of the acid (pKa) and the pH of the aqueous solution. water when strong enough base...

This is a Synthesis of Azo Dyes lab
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....

Construct a flow chart that follows the separation of a mixture
of 2-nitrophenol (an organic acid not used in this experiment with
a pKa = 7.26) and anthracene (neutral organic). Use scheme 1 as a
template. Your reagents available are the same ones used in this
lab.
