Question

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

• A. RX and C₆H₅OH are formed
• B. ROH and C₆H₅X are formed
• C. C₆H₄X₂ and ROH are formed
• D. RX and C₆H₅X are formed

Hint:

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

Answer 1

The Correct Option is B

In the reaction between C₆H₅–O–R and HX, the phenolic group (C₆H₅OH) is formed along with the alkyl halide (C₆H₅X). This is an example of nucleophilic substitution where the alkyl group (R) is substituted by the halide ion (X).
Step 1: Evaluate the reaction.
The O-R bond breaks, and the phenol (C₆H₅OH) is formed along with the alkyl halide (C₆H₅X).
Step 2: Conclusion.
Thus, the correct answer is that ROH and C₆H₅X are formed.
Final Answer: \[ \boxed{\text{ROH and C₆H₅X are formed.}} \]
