Answer

To solve the question regarding the reaction given, we need to identify the type of reaction that occurs when an alkoxide reacts with an alkyl halide to form an ether. Here’s a step-by-step breakdown of the solution:

### Step 1: Identify the Reactants
The reactants in the reaction are:
- An alkoxide ion (CH₃)₃C-O⁻Na⁺ (sodium alkoxide)
- An alkyl halide (CH₃CH₂Cl)

### Step 2: Understand the Reaction
The alkoxide ion acts as a nucleophile and attacks the alkyl halide (CH₃CH₂Cl), leading to the formation of an ether. The reaction can be summarized as:
\[ \text{R-O}^- + \text{R'-X} \rightarrow \text{R-O-R'} + \text{X}^- \]
where R is the alkoxide and R' is the alkyl group from the alkyl halide.

### Step 3: Identify the Product
The product formed from this reaction is an ether:
\[ \text{(CH₃)₃C-O-CH₂CH₃} \]
This indicates that the ether is formed from the alkoxide and the ethyl group from the alkyl halide.

### Step 4: Name the Reaction
The type of reaction that occurs when an alkoxide reacts with an alkyl halide to form an ether is known as the **Williamson Ether Synthesis**.

### Conclusion
Thus, the reaction given in the question is called **Williamson Ether Synthesis**.
