Which compound is formed when `CH_(3)OH` reacts with `CH_(3)MgX` ?

Options

A. Acetone
B. Alcohol
C. Methane
D. Ethane

Answer

To determine the compound formed when methanol (CH₃OH) reacts with a Grignard reagent (CH₃MgX), we can follow these steps:

### Step 1: Identify the Reactants
The reactants in this reaction are methanol (CH₃OH) and a Grignard reagent (CH₃MgX). Methanol is an alcohol, and Grignard reagents are known for their reactivity with acidic protons.

**Hint:** Recognize the functional groups in the reactants and their properties.

### Step 2: Understand the Nature of the Grignard Reagent
Grignard reagents are strong nucleophiles and can react with electrophiles. In this case, the acidic hydrogen (H⁺) in methanol is the electrophile that the Grignard reagent will attack.

**Hint:** Recall that Grignard reagents can react with acidic hydrogens to form alkanes.

### Step 3: Reaction Mechanism
When methanol reacts with the Grignard reagent, the methyl group (CH₃⁻) from the Grignard reagent will attack the hydrogen atom (H⁺) from methanol. This results in the formation of methane (CH₄) and a magnesium alkoxide (MgOCH₃X).

**Hint:** Focus on how the nucleophilic attack leads to the release of hydrogen and the formation of a new compound.

### Step 4: Identify the Products
The products of the reaction are methane (CH₄) and magnesium alkoxide (MgOCH₃X). The main product of interest is methane.

**Hint:** Look for the main product formed from the reaction, which in this case is a simple alkane.

### Conclusion
The compound formed when CH₃OH reacts with CH₃MgX is methane (CH₄).

### Final Answer
The correct answer is option 3: Methane (CH₄).
