A reaction between methyl magnesium bromide and ethyl alcohol gives

Options

A. Butane
B. Ethane
C. Propane
D. Methane

Explanation

To solve the problem of the reaction between methyl magnesium bromide (a Grignard reagent) and ethyl alcohol, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**:
- Methyl magnesium bromide (CH3MgBr)
- Ethyl alcohol (C2H5OH)

2. **Understand the Nature of Grignard Reagents**:
- Grignard reagents are highly reactive organomagnesium compounds that can react with various electrophiles, including alcohols.

3. **Write the Reaction**:
- When methyl magnesium bromide reacts with ethyl alcohol, the Grignard reagent acts as a nucleophile and attacks the electrophilic carbon of the hydroxyl group (–OH) in ethyl alcohol.

4. **Mechanism of Reaction**:
- The hydrogen atom from the hydroxyl group of ethyl alcohol is replaced by the methyl group (CH3) from the Grignard reagent.
- This results in the formation of methane (CH4) and the corresponding magnesium alkoxide (C2H5OMgBr).

5. **Write the Products**:
- The products of the reaction are:
- Methane (CH4)
- Magnesium bromide alkoxide (C2H5OMgBr)

6. **Final Answer**:
- The main product of the reaction is methane (CH4).

### Summary of the Reaction:
The reaction between methyl magnesium bromide and ethyl alcohol produces methane (CH4) and magnesium bromide alkoxide.
