What is the main reason that polar aprotic solvents are favored over polar protic solvents for SN2 reactions?
  1.Polar aprotic solvents dissolve nucleophiles more readily than polar protic solvents.
  2.Polar aprotic solvents destabilize anions.
  3.Polar aprotic solvents stabilize cations, including carbocations.
  4.Polar aprotic solvents form stabilizing hydrogen bonds.
  5.Polar aprotic solvents prevent rearrangements from occurring.

Question 2

When A and B react in t-BuOH, the above rate expression is observed. What is the most likely mechanism of this reaction?
  1.E2
  2.SN2
  3.E1
  4.SN1
  5.It cannot be determined.
 

Question 3

Which of the following SN2 reactions is expected to have the highest rate?
  1.methyl bromide with water in DMSO
  2.ethyl bromide with chloride in methanol
  3.ethyl bromide with hydroxide in HMPA
  4.ethyl chloride with ammonia in acetonitrile
  5.methyl bromide with hydrosulfide (HS) in HMPA
