Which of the following is used as a catalyst in the manufacture of toluene from benzene with `CH_(3)CL`?

Options

A. Ni
B. Anhydrous `AlCl_(3)`
C. Pd
D. Pt

Answer

To solve the question regarding the catalyst used in the manufacture of toluene from benzene with CH₃Cl, we can follow these steps:

### Step 1: Understand the Reaction
The reaction involves benzene (C₆H₆) reacting with methyl chloride (CH₃Cl) to produce toluene (C₆H₅CH₃) and hydrochloric acid (HCl). This is an example of a Friedel-Crafts alkylation reaction.

### Step 2: Identify the Catalyst
In Friedel-Crafts reactions, a catalyst is often required to facilitate the reaction. The common catalysts used for this type of reaction include aluminum chloride (AlCl₃), particularly in its anhydrous form.

### Step 3: Write the Reaction Equation
The chemical equation for the reaction can be written as follows:
\[ C_6H_6 + CH_3Cl \xrightarrow{AlCl_3} C_6H_5CH_3 + HCl \]
Here, AlCl₃ acts as the catalyst.

### Step 4: Select the Correct Option
Given the options (which are not provided in the question), we can conclude that the correct catalyst used in this reaction is anhydrous aluminum chloride (AlCl₃).

### Final Answer
The catalyst used in the manufacture of toluene from benzene with CH₃Cl is **anhydrous AlCl₃**.
