why is it not possible to prepare ditertiary butyl ether by Williamson's synthesis ?

Explanation

To understand why it is not possible to prepare di-tertiary butyl ether by Williamson's synthesis, we need to analyze the mechanism of the Williamson ether synthesis and the structure of the reactants involved.

### Step-by-Step Solution:

1. **Understanding Williamson's Synthesis**:
Williamson's synthesis is a method for preparing ethers by reacting an alkoxide ion with a primary or secondary alkyl halide. The general reaction can be represented as:
\[
R'X + R''O^- \rightarrow R''O-R' + X^-
