Reaction of ethyl halide with alkoxide is called:

Options

A. Wurtz reaction
B. Kolbe's reaction
C. Wiliamson reaction
D. Carbylmine reaction

Explanation

To solve the question "The reaction of ethyl halide with alkoxide is called:", we will analyze the options and determine the correct answer step by step.

### Step-by-Step Solution:

1. **Identify the Reactants**:
- The reactants mentioned are ethyl halide and alkoxide. Ethyl halide can be represented as CH3CH2X, where X is a halogen (like Cl, Br, or I). Alkoxide is typically represented as R-O^-, where R is an alkyl group.

2. **Understand the Reaction Type**:
- The reaction between an alkyl halide and an alkoxide is a nucleophilic substitution reaction. The alkoxide ion acts as a nucleophile and attacks the carbon atom bonded to the halogen in the ethyl halide.

3. **Mechanism of the Reaction**:
- In this reaction, the alkoxide ion (R-O^-) attacks the electrophilic carbon atom of the ethyl halide (CH3CH2X). This leads to the displacement of the halogen atom (X) and the formation of an ether. The general reaction can be summarized as:
\[ CH3CH2X + R-O^- \rightarrow CH3CH2OR + X^- \]
- The product formed is an ether (CH3CH2OR).

4. **Name of the Reaction**:
- This specific reaction is known as **Williamson's Ether Synthesis**. It is a well-known method for synthesizing ethers from alkyl halides and alkoxides.

5. **Conclusion**:
- Therefore, the reaction of ethyl halide with alkoxide is called Williamson's reaction.

### Final Answer:
The reaction of ethyl halide with alkoxide is called **Williamson's reaction**.
