Question

Sn1 reactions are effected by solvent. Can you just explian what the predicted order will be and why.

Arrange the four test tubes in the test tube stand. In the first test tube, add 1 mL 1: 1 of methanol: water solvent solution. In the second tube, add 1 mL of a 1: 1 ethanol: water solvent solution. In the third tube, add 1 mL of a 1: 1 1-propanol: water solvent solution. In the fourth and final tube, add 1 mL of a 1: 1 acetone: water solvent solution. Into each test tube, place 3 drops of 0.5 M NaOH and 3 drops of 1% phenolphthalein solution. Finally, add 3 drops of the 2-bromo-2-methylpropane(lert-butylbromide) to each test tube. In your lab notebook, record the exact time (hour/minute second) that the first drop is added to each tube. Once the alkyl halide has been added, cover and shake each tube to ensure proper mixing of the reagents. Watch for the dissipation of the pink coloration and record the precise time that it occurs for each individual reaction. Use a table format similar to the one shown below to organize your data. Tubes 1-4 offer a comparison of solvent systems of differing polarities as related to a specific S_N 1
