Write the names of the reagents and equations for the preparation of the following ethers by Williamson's synthesis :
(i) 1- Propoxypropan`" "` (ii) 2-Methoxy-2-methylpropane `" " ` (iii) Ethoxybenzene `" " `(iv) Methoxyethane.

Explanation

To prepare the given ethers using Williamson's synthesis, we will follow these steps for each ether:

### (i) Preparation of 1-Propoxypropane

1. **Reagents**: Sodium propoxide (C3H7O^-Na^+) and 1-bromopropane (C3H7Br).
2. **Reaction**:
\[
\text{C3H7O}^- \text{Na} + \text{C3H7Br} \rightarrow \text{C3H7O-C3H7} + \text{NaBr}
