Which one is formed when sodium phenoxide is heated with ethyl iodide?

1. Phenetole
2. Ethyl phenyl alcohol
3. Phenol
4. None of these

Correct answer: Phenetole

Solution

When sodium phenoxide reacts with ethyl iodide, an ethyl group replaces the sodium ion, forming phenetole (ethyl phenyl ether). This is a classic example of the Williamson ether synthesis.
