Assertion : Rate of reaction of alkyl halide in Williamson's synthesis reaction is 1^ R X>2^ R X>3^ R X . Reason : It is a type of bimolecular substitution reaction (S_ N 2 ) .

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer

A. If both assertion and reason are true and reason is the correct explanation of assertion.

Step-by-step solution

Williamson's synthesis occurs by S _N 2 mechanism and primary alkyl halides are most reactive in S _ N 2 reactions.
