Which of the following is the correct order of decreasing SN2 reactivity?

Multiple Choice Options

  • A RCH2X > R3CX > R2CHX
  • B RCH2X > R2CHX > R3CX
  • C R3CX > R2CHX > RCH2X
  • D R2CHX > R3CX > RCH2X

Step-by-Step Verified Solution

In SN2 mechanism transition state is pentavelent. For bulky alkyl group it will have sterical hinderance and smaller alkyl group will favour the SN2 mechanism. So the decreasing order of reactivity of alkyl halides is RCH2X>R2CHX>R3CX
