Name the pair of alkyl halide and alkoxide for the preparation of ethyl tert-butyl ether.

Explanation

To prepare ethyl tert-butyl ether, we can follow these steps:

### Step 1: Understand the Structure of Ethyl tert-butyl Ether
The structure of ethyl tert-butyl ether can be represented as:
\[ \text{C}_2\text{H}_5\text{O}\text{C}(\text{CH}_3)_3 \]
This indicates that the ether consists of an ethyl group (C2H5) and a tert-butyl group (C(CH3)3) connected by an oxygen atom.

### Step 2: Identify the Alkyl Halide
