Why is diethyl ether used as solvent in the prparation of Grignard reagents ?

Explanation

### Step-by-Step Solution:

1. **Understanding Ethers**:
- Ethers are organic compounds characterized by the general formula ROR, where R represents alkyl groups and O is an oxygen atom. Each oxygen atom in ethers has two lone pairs of electrons.

2. **Ethers as Lewis Bases**:
- Due to the presence of lone pairs of electrons on the oxygen atom, ethers can act as Lewis bases. This means they can donate a pair of electrons to Lewis acids.
