Reason : Alkyl aryl ethers on reaction with halogen acid always form aryl halide due to formation of highly stable carbocation.

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

D. If both assertion and reason are false.

Step-by-step solution

In case of alkyl aryl ethers, the products are always phenol and alkyl halide and never an aryl halide and alcohol. This is due to the fact that O - C ₆ H ₅ bond has partial double bond and is stronger than O - R bond. Therefore, halide ion exclusively breaks the O -R bond forming alkyl halide and phenol.
