For the Diels Alder lab, you recrystallized your product in toluene. Which of the following do you expect to happen after recrystallization? Recrystallization in Toluene will cause hydrolysis of the acid anhydride, giving you a carboxylic acid byproduct. The melting point of your product goes from 240-250 Celsius before recrystallization to 262-264 Celsius after recrystallization. The melting point of your product goes from 262-264 Celsius before recrystallization to 240-250 Celsius after recrystallization. Recrystallization completes the reaction and pushes equilibrium toward...
