Write the equations of the following reactions:
i. Friedel-Crafts reaction - alkylation of anisole.
ii. Nitration of anisole.
iii. Brominatation of anisole in ethanoic acid medium.
iv. Fridel-Crafts acetylation of anisole.

Explanation

To solve the question, we will write the equations for the four reactions involving anisole.

### Step-by-Step Solution:

#### i. Friedel-Crafts Reaction - Alkylation of Anisole
1. **Reactants**: Anisole (C6H5OCH3) and chloromethane (CH3Cl) in the presence of anhydrous aluminum chloride (AlCl3).
2. **Reaction**:
