D. Gattermann

Answer

To determine the name of the reaction given in the question, we can analyze the reaction step by step.

### Step 1: Identify the Reactants
The reactants in the reaction are:
- Benzene (C₆H₆)
- Methyl chloride (CH₃Cl)

### Step 2: Identify the Catalyst
The reaction is carried out in the presence of anhydrous aluminum chloride (AlCl₃), which acts as a Lewis acid catalyst.

### Step 3: Understand the Reaction Type
The reaction involves the substitution of a hydrogen atom in benzene with a methyl group from methyl chloride. This type of reaction is known as an electrophilic substitution reaction, where the benzene ring, which is rich in electron density, reacts with an electrophile.

### Step 4: Formation of Electrophile
In the presence of AlCl₃, methyl chloride (CH₃Cl) forms a methyl cation (CH₃⁺), which is a strong electrophile. The reaction can be represented as:
\[ \text{CH}_3\text{Cl} + \text{AlCl}_3 \rightarrow \text{CH}_3^+ + \text{AlCl}_4^- \]

### Step 5: Electrophilic Attack
The methyl cation (CH₃⁺) then attacks the benzene ring, leading to the formation of toluene (C₆H₅-CH₃) and the release of HCl as a byproduct:
\[ \text{C}_6\text{H}_6 + \text{CH}_3^+ \rightarrow \text{C}_6\text{H}_5\text{-CH}_3 + \text{HCl} \]

### Step 6: Identify the Name of the Reaction
This reaction is specifically known as a **Friedel-Crafts Alkylation** reaction. It is a classic example of electrophilic aromatic substitution where an alkyl group is introduced into an aromatic ring.

### Final Answer
The name of the above reaction is **Friedel-Crafts Alkylation**.
