crystallized instantaneously
Part B: Solvent Effects on SN1
Complete the following table to record the times at which thephenolphthalein indicator becomes clear (t1/2).
Which group of solvents did you analyze?
Solvent system and t1/2
Selected solvent systems for Group D and the times toneutralization
Solvent Ratio
Solvent System
t1/2 (sec)
Solvent 1
Solvent 2
Solvent 3
Part A: Substrate effects on SN1 andSN2
Write equations for the reactions investigated. LabelSN1 or SN2.
Write conclusions based on the results above. Discuss thenucleophile, the leaving group, the substrate, and any relevantfactors that affected the substitution reaction?
Compare the relative rate of the reaction
Conclusion: Discuss solvent effects
