Question

Anisole can be prepared by the action of methyl iodide on sodium phenate. The reaction is called:

• A. Wurtz reaction
• B. Williamson's reaction
• C. Fittig's reaction
• D. Etard's reaction

Answer 1

The correct option is B Williamson's reaction

Anisole can be prepared by the action of methyl iodide on sodium phenate. The reaction is called Williamson's reaction.
$\underset{\text{phenol}}{C_6{H}_5-OH}+NaOH\to \underset{\text{sodium phenoxide}}{C_6{H}_5-ONa}\stackrel{\underset{\text{methyl iodide}}{C{H}_3-I}}{\to }\underset{\text{anisole}}{C_6{H}_5-O-C{H}_3}$
Williamson's reaction can be used for the preparation of simple as well as mixed ethers.
