Question

Among the following product the products formed by the reaction of anisole with HI are

• A. Benzene + Methanol
• B. Phenol + Iodomethane
• C. Phenol + Methane
• D. Sodium phenate + Methanol

Answer 1

The Correct Option is B

Anisole, also known as methoxybenzene, is a compound with the formula \(\text{C}_6\text{H}_5\text{OCH}_3\). When anisole reacts with hydrogen iodide \((\text{HI}),\) it undergoes a nucleophilic substitution reaction known as the \((\text{HI})\) cleavage reaction.
The reaction can be represented as follows:
\(\text{C}_6\text{H}_5\text{OCH}_3 + \text{HI} \rightarrow \text{C}_6\text{H}_5\text{OH} + \text{CH}_3\text{I}\)
In this reaction, the methoxy group \(-\text{OCH}_3\) of anisole is replaced by an iodine atom from \((\text{HI}),\) resulting in the formation of phenol \((\text{C}_6\text{H}_5\text{OH})\) and iodomethane \((\text{CH}_3\text{I})\)
Therefore, the correct products formed by the reaction of anisole with \((\text{HI})\) are phenol and iodomethane (option B).
