The reaction can be classified as:
- Alcohol formation reaction
- Dehydration reaction
- Williamson alcohol synthesis reaction
- Williamson ether synthesis reaction
The Correct Option is D
Solution and Explanation
Williamson Ether Synthesis Reaction
The reaction is a typical example of the Williamson ether synthesis method, which involves the formation of an ether from an alkyl halide and an alkoxide ion. This reaction is a nucleophilic substitution where the alkoxide ion attacks the alkyl halide, displacing the halide ion and forming an ether.
The general reaction can be written as:
\(R - X + R - ONa → R - O - R + NaX\)
Explanation:
- R - X: Alkyl halide (e.g., alkyl chloride or bromide).
- R - ONa: Alkoxide ion (formed by reacting alcohol with a sodium metal or sodium hydride).
- R - O - R: The ether product formed after the nucleophilic substitution.
- NaX: The sodium halide (e.g., NaCl or NaBr) formed as a by-product.
Conclusion:
The Williamson ether synthesis is an important method for preparing ethers in organic chemistry through a nucleophilic substitution mechanism.

What is Alcohol?
Alcohol is a derivative of water (H2O) that has one, two, or more hydroxyl groups that are attached to a carbon atom of a hydrocarbon chain (an alkyl group). It is one of the most common organic compounds used in sweeteners, fragrances, and medicine.

Uses of Alcohol:
- Ethanol is the alcohol used in alcoholic drinks. It can be used as an industrial methylated spirit where methanol is used very little in quantity as it can be dangerous.
- It is used as fuel to produce carbon dioxide and water by the process of fermentation. Whereas methanol burns carbon dioxide and water to facilitate combustion.
- Alcohol is an organic compound used as a solvent that is insoluble in water.
- It can be used to lower the level of sugar.
- Alcohol is used as a preservative in laboratories.
