During this experiment, you will test the effect of a variety of solvents on the rearrangement of a
methoxy-spiropyran molecule: 8-methoxy-1',3'-dihydro-1',3',3'-trimethyl-6-nitrospiro[2H-1- benzopyran-2-2'-2H-indole] (shown above). As part of your pre-lab assignment, you should consider the questions below and record your answers in your laboratory notebook before coming to lab:
Hypothesize which of the following solvents will be the most effective in opening the SP ring: acetone, methanol, ethanol, or acetonitrile. Rank them in order from most effective (darkest color) to least effective (lightest color), and explain your prediction.
