Give balanced equations for the following name reactions :
Williamson's synthesis.

Explanation

To provide a balanced equation for Williamson's synthesis, we will follow these steps:

### Step 1: Identify the reactants
In Williamson's synthesis, the reactants are an alkyl halide and a sodium alkoxide. For this example, we will use methyl bromide (CH3Br) as the alkyl halide and sodium ethoxide (C2H5ONa) as the sodium alkoxide.

### Step 2: Write the reaction
The reaction involves the alkyl halide reacting with the sodium alkoxide to form an ether and a sodium halide. The general form of the reaction is:
\[ \text{R-X} + \text{R'-O}^{-} \text{Na}^{+} \rightarrow \text{R'-O-R} + \text{NaX} \]
