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.
