Write the structural formula of the main organic product formed when ethyl acetate is treated with double the molar quantity of `MeMgBr` and the reaction mixture is poured into `H_2 O`.

Explanation

To solve the problem of determining the main organic product formed when ethyl acetate is treated with double the molar quantity of methyl magnesium bromide (MeMgBr) and then poured into water, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**:
- Ethyl acetate (C2H5COOCH3) is an ester.
- Methyl magnesium bromide (MeMgBr) is a Grignard reagent.
