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

Answer: (B)

Phenol + Iodomethane

Answer 2

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).
