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....
