Question

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

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (D)

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—C₆H₅ 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.
