Question:medium

What happens when C₆H₅–O–R is treated with HX?

Show Hint

When an ether (C₆H₅–O–R) reacts with HX, it undergoes cleavage at the oxygen atom, forming a phenol and an alkyl halide.

  • RX and C₆H₅OH are formed
  • ROH and C₆H₅X are formed
  • C₆H₄X₂ and ROH are formed
  • RX and C₆H₅X are formed
Show Solution

The Correct Option is B

Solution and Explanation

In the reaction of C₆H₅–O–R with HX, phenol (C₆H₅OH) and an alkyl halide (C₆H₅X) are produced. This is a nucleophilic substitution where the halide ion (X) replaces the alkyl group (R).
Step 1: Reaction Analysis.
The O-R bond cleaves, resulting in the formation of phenol (C₆H₅OH) and alkyl halide (C₆H₅X).
Step 2: Final Determination.
Therefore, the products are ROH and C₆H₅X.
Final Answer: \[\boxed{\text{ROH and C₆H₅X are formed.}}\]
