In the reaction `: CH_3 MgCl + NH_3 to ? ` The product is :

Options

A. `CH_3NH_2`
B. `CH_4`
C. `CH_3MgNH_2`
D. `CH_3Cl`

Answer

To solve the reaction of CH₃MgCl with NH₃, we can follow these steps:

### Step 1: Identify the Reactants
The reactants in the reaction are CH₃MgCl (a Grignard reagent) and NH₃ (ammonia).

### Step 2: Understand the Nature of the Grignard Reagent
CH₃MgCl is a Grignard reagent. In this compound, the carbon (C) in CH₃ has a partial negative charge (δ-) due to the electronegativity difference between carbon and magnesium. The magnesium (Mg) has a partial positive charge (δ+).

### Step 3: Recognize the Acidity of Ammonia
In ammonia (NH₃), the hydrogen atoms attached to nitrogen are considered acidic hydrogens because nitrogen is electronegative and can stabilize the negative charge when it loses a hydrogen ion (H⁺).

### Step 4: Reaction Mechanism
The CH₃⁻ (from CH₃MgCl) will act as a nucleophile and attack one of the acidic hydrogens (H⁺) from NH₃. This results in the formation of methane (CH₄) and a negatively charged amide ion (NH₂⁻).

### Step 5: Formation of Products
The reaction produces:
1. Methane (CH₄)
2. The magnesium ion (Mg²⁺) combines with the amide ion (NH₂⁻) to form magnesium amide chloride (MgNH₂Cl).

### Final Products
Thus, the final products of the reaction are:
- CH₄ (methane)
- MgNH₂Cl (magnesium amide chloride)

### Conclusion
The correct answer to the question is CH₄ (methane).
