How does benzene react with,
`C_(2)H_(5)Cl` in the presence of `AlCl_(3)`

Explanation

To solve the question of how benzene reacts with C2H5Cl in the presence of AlCl3, we can break it down into several steps:

### Step 1: Identify the Reactants
The reactants in this reaction are benzene (C6H6) and ethyl chloride (C2H5Cl), with aluminum chloride (AlCl3) acting as a catalyst.

### Step 2: Role of Aluminum Chloride
Aluminum chloride (AlCl3) is a strong Lewis acid. It interacts with ethyl chloride (C2H5Cl) to form a more reactive species. When AlCl3 reacts with C2H5Cl, it abstracts the chlorine atom, leading to the formation of an ethyl cation (C2H5+) and AlCl4-.
